The operation of the apparatus shown in FIGS. 1 and 2 will be described in detail below according to the flow chart.

<Initial operation (SP1 in FIG. 4)> When the power is turned on and the seat 6 is loaded, the head 7
Is accessed from the outermost side of the seat 6 to the queue track. During this access, the switch 5 is connected to the D terminal, and the reproduction signal from the head 7 is input to the envelope detector 17. When there is an envelope for each information track, that is, when a video signal is recorded in the information track, the address is input to the RAM in the control unit 16.
Then, when the track number TK becomes 51, that position is the queue track, so the movement of the head 7 is stopped there. Then, the switch 14 is connected to the F terminal to reproduce the data signal. The reproduced data is stored in RAM.

After that, the selection switch 25 of the automatic control mode (auto) and the manual control mode (manual) is read, and different processing is performed depending on whether it is automatic or manual.

<Source mode (automatic control mode) (SP2 in FIG. 4)> When the source mode switch 27 is pressed, the recording condition data of the queue track stored in the RAM is transferred to the CPU. The recording condition data includes selection of color recording and monochrome recording, how many times recording is performed, and the like. If there is no empty track based on the empty track data detected in SP1, the display section 18 displays that there is no empty track and prompts the replacement of the seat 6. If there is an empty truck, the head is accessed to the smallest track address of the empty truck. Then, the condition of color recording or monochrome recording is set, and the switch 3 is connected to the A terminal. In that state, the user waits for the recording switch 23 to be pressed. When the recording switch 23 is pressed, the switch 5 is connected to the C terminal to record one field or one frame.

When recording is completed, the empty track data in RAM is rewritten, and if there is recording, the above operation is repeated.

<Playback Mode (Automatic Control Mode) (SP3 in FIG. 5)> Next, the case where the playback switch 24 is pressed in the automatic control mode will be described. First, the reproduction condition data is transferred to the CPU, and the first information track is accessed according to the condition of the reproduction order. Then, the switch 5 is connected to the D terminal and the switch 14 is connected to the E terminal, and the reproduction is started. Then, the timer measures the time according to the condition of the reproduction time, and when the time measurement ends, the next track is accessed. When all the reproduction is completed, the process returns to D, and the repeated reproduction is performed.

Note that the tracks that can be accessed during playback are limited to information tracks, and access to the queue tracks is prohibited.

Further, the switch 25 is switched to the manual mode during the automatic reproduction to shift to the manual reproduction mode.

<Print Mode (Automatic Control Mode) (SP4 in FIG. 5)> A case where the print mode switch 28 is turned on by the mode will be described. First, print condition data (print track number, number of prints, print size, etc.) is stored in the CPU.
Then, the head 7 is accessed to the first print track, the switch 5 is connected to the D terminal, and the switch 14 is connected to the E terminal to reproduce the video signal. In this state, the start of printing is output to a printer (not shown).

When one print is completed, check whether the specified number of prints have been completed. When the print of that track is completed, if there is another track print, move the head 7 to print. Run. Then, when all the printing operations are completed, the print mode is released.

<Data input mode (SP5 in FIG. 6)> When the data input mode is selected by the data input mode switch (not shown), the data input keyboard 19 (FIG. 1)
The data input from is temporarily written in the RAM in the control unit 16. When the input is completed, the head 7 accesses the queue track, the switch 3 is connected to the B terminal and the switch 5 is connected to the C terminal, and the data in the RAM is recorded on the queue track.

<Power Off Mode (SP6 in FIG. 6)> When the power switch (not shown) is turned off, the head is accessed to the queue track, and the data in the RAM is recorded on the queue track. When the data recording is completed, the power is turned off and the operation ends.

<Source mode (manual) (SP7 in FIG. 7)> In the manual source mode, first, empty track data detected in the initial operation is read out, and if there is no empty track, the empty track is displayed on the display unit 18. If there is an empty truck, the head is accessed to the lowest address of the empty truck.
Then, the track feed speed in the case of continuous recording input from the operation key input means 15 is read. Then, the switch 3 is connected to the A terminal, and the input of the recording switch 23 is waited for.
When there is a recording command from the recording switch 23, the switch 5 is connected to the C terminal and recording is performed. Switch 5 when recording is completed
Is connected to the D terminal, the empty track data in the RAM is rewritten, and the above operation is repeated in the case of continuous recording.

<Playback mode (manual) (SP8 in FIG. 7)> The empty track data is read and the head is accessed to the minimum address of the recorded track already recorded. The track feed speed during continuous playback is read, switch 5 is connected to the D terminal and switch 14 is connected to the E terminal, and playback is started.

Then, in the case of continuous reproduction, the time timer corresponding to the track feed speed operates, and the head 7 is accessed to the next recording track when the timer finishes timing. In this way, the video signal is reproduced from all the recording tracks.

In the case of non-continuous reproduction, when a track switching command is input by a switching switch (not shown), the next recording track is accessed.

Headset access to the key track is also prohibited in the manual playback mode.

<Print mode (manual) (SP9 in FIG. 8)> When the print mode is selected by the print mode switch 28, the empty track data is first read and the head is accessed to the minimum address of the recording track. The switch 5 is connected to the D terminal and the switch 14 is connected to the E terminal, and the video signal is reproduced from each recording track for a predetermined time.
The user presses the print switch 26 when there is a reproduced image to be printed while monitoring the reproduced image. When the print switch 26 is pressed, printing is started by a printer (not shown), and the apparatus continues reproduction until the designated number of prints are completed.

<Summary of Operation> As described above, in the present embodiment, since the empty track and the recorded track are discriminated during the head access to the queue track, the empty track is accessed during recording and the recorded track is accessed during reproduction. Can be accessed in an extremely short time.

In addition, the head can be directly accessed to the minimum address of the empty track at the time of manual recording and directly to the minimum address of the recorded track at the time of manual reproduction.

Further by first accessing the Kyutrak,
Whenever the automatic control mode is selected, it is not necessary to access the queue every time the automatic control mode is selected, and extremely automatic and manual switching can be performed smoothly.

In this embodiment, the magnetic sheet is used as the recording medium, but it is of course possible to use other recording medium such as an optical disc.
