In recent years, miniaturization, weight reduction, and personalization of OA equipment have progressed, and there has been a demand for higher performance in its functions. Considering an electronic notebook as an example, the miniaturization is progressing compared with the conventional one, and functionally, the schedule recording, the telephone directory function, various dictionary functions, and the database function are realized. An IC memory card is used to realize these functions. In printers and the like, various fonts are stored in an IC memory card and can be used as options. Further, an IC memory card is optionally used to increase the storage capacity of the personal computer.

However, in the application of these IC memory cards, an increase in storage capacity has been demanded.
The memory capacity of a single memory card is limited to a few megabytes, and we cannot expect a very large capacity. Also, IC
Currently, the unit price per storage capacity of a memory card is high.

Under these circumstances, the diameter has recently been 2.
Using a 5-inch or 1.8-inch magnetic disk as a storage medium, a large-capacity / ultra-compact / low-priced HDD with a storage capacity of several tens of megabytes to hundreds of tens of megabytes has been developed.
It is becoming portable.

Since such an ultra-compact HDD is portable and has a large storage capacity, it can be used in the same manner as the above-mentioned IC memory card.

However, when the HDD is used together with the IC memory card in the personal computer, a dedicated slot and connector for mounting the IC memory card in the personal computer, and an HD
A dedicated slot for mounting D and a connector must be provided separately, and it is difficult to provide these two slots in a miniaturized personal computer, and this leads to an increase in price. It was

The present invention has been made in view of the above points.
Therefore, using the slot / interface signal / connector for the IC memory card, the personal computer body
It is an object of the present invention to provide a disk storage device that can be directly mounted on a disk .
