2. Description of the Related Art Conventionally, as an apparatus for recording and reproducing information,
2. Related Art A cassette tape recorder that uses a magnetic tape as a recording medium and records or reproduces audio information is generally known. The advantages of using a magnetic tape in a cassette tape recorder include that the cost of the magnetic tape itself is low, and that the long tape length enables long-time recording and reproduction. On the other hand, since sound is recorded on the magnetic tape by the relative movement of the magnetic head and the magnetic tape, a mechanism for moving the magnetic tape is required. As a result,
As disadvantages, it is difficult to reduce the size and weight of the device, and since it operates mechanically, there are problems such as occurrence of mechanical noise, high failure rate, and low access speed. .

In order to solve the above-mentioned problems, an audio recording / reproducing apparatus using a semiconductor storage device instead of a magnetic tape as a recording medium has been developed.

[0004] This device does not record or reproduce sound using a magnetic recording phenomenon due to mechanical relative movement as in a device using a magnetic tape, but uses an electric charge accumulation state. To record audio.
Therefore, since the above-mentioned mechanism is unnecessary in this device, it is easy to reduce the size and weight of the device, no mechanical noise is generated, and the reliability can be improved. In addition, since all recording and reproducing operations are performed electrically, the access speed for searching for a desired voice becomes high,
It is possible to instantaneously search for a desired sound. On the other hand, semiconductor storage devices generally have a disadvantage that they are somewhat expensive and require a backup power supply to hold stored data, but in recent years, due to the development of semiconductor manufacturing methods, they have been relatively inexpensive.

If you want to record song C between song A and song B when song B and song B have already been recorded, song B was once recorded on another tape, and song C was recorded after song A After that, the music B must be recorded again, and the operation becomes complicated, and there is a problem that the operability is poor.

In an apparatus using a non-volatile batch erasing memory as a medium, the non-volatile batch erasing memory may record a voice once and erase a predetermined batch erasing area before recording a new voice. However, there is a problem that overwrite recording cannot be performed in real time and operability is poor.

At the time of recording, the sound is converted into an electric signal (analog signal) by the microphone 2, amplified by the amplifier 3, and then converted from an analog signal to a digital signal by the AD converter 4. The converted digital audio signal is compressed by the audio compression circuit 5 to reduce the amount of information to several tenths to tenths and output to the system microcomputer 7. The system microcomputer 7 reads the compressed data once, and writes the compressed data into the memory card 6 by designating a predetermined address.

Hereinafter, in this embodiment, audio is recorded as a plurality of divided units (hereinafter, referred to as documents), and an index, which is sub-information for each document, is recorded. Data, elapsed time data, codes indicating the attributes of the index, and the like are recorded. The index is, for example, one unit of 8 bytes, and the audio data is, for example, one unit of 34 bytes. The indexes are sequentially recorded from the highest address side of the memory card 6 to the lowest address side. The voice data uses 1 byte of the 34 bytes as a flag byte.

Referring to step S1 of FIG. 3 and (a) of FIG. 4, first, the information recording / reproducing apparatus is in an initial state.
The initial state refers to, for example, a state where reproduction is stopped at an arbitrary position. Next, in step S2, the system microcomputer 7 determines whether or not the recording is the insertion recording by the key switch 12. When recognizing that it is insertion recording, in step S3, the following pre-processing of insertion recording is performed.

Referring to FIG. 4B, the system microcomputer 7 first writes the jump flag J1 to the flag byte of the audio frame at the address of the recording start position, and also jumps to the flag byte of the audio frame at the jump destination. Write the flag j1.

Referring to FIG. 5, the system microcomputer 7 comprises:
The index X1 includes a jump mark code, a recording start position address (J1 address), and a jump destination address (j
One address, where the jump destination is the same as the physical EOD (end of data) address) is recorded. Next, the time mark code and the start time (TIME t1) are recorded in the index X2. Insertion section time (TIM
Et2) is recorded at the end of recording. The time index is used for adjusting the elapsed time after the insertion position in the skip function, and is not directly related to the insertion recording.

Upon confirming that the insert button has been released, the system microcomputer 7 executes the post-processing of the insertion recording as described below.

First, the system microcomputer 7 writes the jump flag J2 in the flag byte of the frame at the address of the recording end position. Next, the jump mark code and the recording end position address (J2
Address) and return address (J1 address, where
The return destination is the same address as the recording start position. ). Next, the insertion section time (TIME t2) is recorded in the time adjustment index X2. Next, the physical EOD position is recorded in the index X4.

When the system microcomputer 7 detects a jump flag in the flag byte, in step S13,
Only the index of the jump mark code is searched from the index shown in FIG. 5, and the address currently being reproduced is compared with the address written in the index. That is, the J1 address and the J2 address are compared. Since the address currently being reproduced is equal to the J1 address, the system microcomputer 7 sets the index X shown in FIG.
The address of the jump destination (j1 address) is extracted from 1. Next, in step S14, the IP of FIG.
A jump is performed as shown in FIG. Here, the jump flag J1 at the jump destination is set to be ignored.

For example, from IR1 in FIG. 4E, the system microcomputer 7 continues rewinding while checking the flag byte. Next, upon detecting the jump flag in the flag byte, the system microcomputer 7 searches only the index of the jump mark code from the index of FIG. 5 and compares the current address with the address written in the index. That is, the j1 address and the J1 address of the index X3 are to be compared. In this case, since the current address is equal to the J1 address of the index X3, the jump destination address (J2 address) is extracted from the index X3, as shown in IR2. Perform a jump to. Here, the jump flag J2 at the jump destination is set to be ignored.

Next, when the next jump flag j1 is detected during rewind by IR3, the system microcomputer 7 extracts the jump destination address (J1 address) from the index in FIG. And the rewind is continued as indicated by IR5.

In step S23, the system microcomputer 7 performs the following preprocessing of overwrite recording.

First, as shown in FIG. 8B, the system microcomputer 7 writes the jump flag K1 in the flag byte of the frame at the address of the recording start position, and also jumps to the flag byte of the audio frame to which the jump is made. Write the flag k1.

Next, the jump mark code, the recording start position address (K1 address), and the jump destination address (k1 address, the jump destination is the physical EOD address) are recorded in the index X1 shown in FIG.

Next, in step S24 of FIG. 7, the system microcomputer 7 records the audio data in the unrecorded portion of the memory card 6, as indicated by the solid arrow in FIG. At this time, the system microcomputer 7 counts up the address of the portion to be overwritten by an amount corresponding to the overwrite recording time, as indicated by the dashed arrow.

Next, in step S25, the system microcomputer 7 checks whether or not the key switch 12 has shifted to the end of recording.

When recognizing that the recording has ended, in step S26, the system microcomputer 7 executes the following overwrite recording finishing process.

First, as shown in FIG. 8C, the system microcomputer 7 writes the jump flag K2 in the flag byte of the frame at the address of the recording end position, and also jumps to the flag byte of the return audio frame. Flag k2
To write. Next, a jump mark code, a recording end position address (K2 address), and a jump destination address (k2 address) are also recorded in the index x2 of FIG. Here, the k2 address is an address of a portion corresponding to the overwriting time.

Next, the physical E is added to the index x3 of FIG.
Record the OD position. Next, in step S27, the system microcomputer 7 ends the recording, and shifts to the stop mode.

Next, the operation of reproducing the overwritten portion will be described. FIG. 10 is a flowchart for explaining a reproduction operation of overwrite recording.

First, in step S31, the system microcomputer 7 reproduces audio data from EP1 of FIG. 8D.

Next, in step S32, the system microcomputer 7 checks the flag byte of the audio frame and detects a jump flag.

When a jump flag is detected, step S
At 33, the system microcomputer 7 searches only the index of the jump mark code from the index of FIG. 9, and compares the current address with the address written in the index. That is, the K1 address and the k2 address are compared. The current address is K1
Since it is equal to the address, the jump destination address (k1 address) is extracted from the index x1.

Next, the system microcomputer 7 executes a jump as shown in EP2 of FIG. 8D. Here, the jump flag k1 at the jump destination is set to be ignored.

Thereafter, steps S31 to S34 are similarly repeated, and when the system microcomputer 7 detects the next jump flag K2 during reproduction at EP3 in FIG. 8D, the jump destination address (from the index in FIG. 9) After the jump is executed as shown in EP4, the reproducing operation is continued as shown in EP5.

Next, the operation at the time of rewind will be described with reference to FIG. At the time of rewind,

The system microcomputer 7 continues rewinding while checking the flag byte from ER1 in FIG. 8 (e).

Next, when the system microcomputer 7 detects the jump flag in the flag byte, it searches only the index of the jump mark code from the index of FIG. 9 and compares the current address with the address written in the index. . That is, the k1 address and the k2 address are to be compared. Since the current address is equal to the k2 address, the jump destination address (K2 address) is extracted from the index x2, and the jump is executed as indicated by ER2. Here, the jump flag K2 at the jump destination is set to be ignored.

Next, when the system microcomputer 7 detects the next jump flag k1 during rewinding in ER3, the system microcomputer 7 extracts the jump destination address (K1 address) from the index in FIG. After executing the jump, rewinding is continued as indicated by ER5.

By the above-described overwrite recording operation, the overwrite sound data can be overwritten at an arbitrary position of the already recorded audio data, and the overwrite recording operation can be executed in real time. Operability is greatly improved.

Steps S6 and S47 are the same as steps S31 to S34 shown in FIG.

In the flowchart shown in FIG. 11, in step S43, it is determined whether or not the currently reproduced data is overwrite data. If the data is not overwrite data, the flow shifts to step S46 to perform overwrite recording shown in FIG. The same operation as the reproduction operation is performed. If the data is overwrite data, the flow shifts to step S45 to forcibly change the jump destination address to the jump source address (RE in FIG. 12 (d)).
(In the case of P3, the K1 address) and set in step S4
The jump is executed according to the jump source address set in step 7.

The above-mentioned recover reproduction operation will be described in more detail with reference to FIG. The system microcomputer 7 is shown in FIG.
