Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a cartridge type disk device.

0002

[Conventional technology]

Cartridge-type disk devices allow you to easily increase storage capacity by replacing the storage medium. In addition, it is possible to manage data separately for individuals and jobs for each cartridge. It has been put into practical use.

0003 Conventionally, this type of cartridge-type disk device has a cartridge cartridge as shown in FIG. A hard disk drive 2a and a control circuit board 3a are installed inside the housing 1a of the chassis 6a. It is composed of: The I/O connector 4 on the control circuit board 3a is the main body of FIG. By inserting the cartridge 6a into the slot 7 of the device 8, electricity is supplied to the main device 8. connected.

[Problem that the idea aims to solve]

The conventional cartridge-type disk device mentioned above uses the hard disk There are several microns between the magnetic head where the drive reads data and the storage medium disk. Moreover, the magnetic head is made of metal and is hard, but the surface of the storage medium is soft, so it can be easily shocked. When the magnetic head collides with the storage medium, it scrapes the storage medium along with the data. Therefore, since the earthquake resistance and impact resistance are very weak, it is difficult to store the cartridge. However, the disadvantage is that data storage during transportation is unreliable.

[0005]

[Means to solve the problem]

The cartridge-type disk device of this invention allows for easy storage by replacing cartridges. In a cartridge-type disk device that can increase capacity, a semiconductor is attached to the cartridge. A semiconductor disk using physical memory is used, and the data on the semiconductor disk is A battery for storage is built into the cartridge, and a battery is further inserted into the cartridge. It has a battery indicator that displays the remaining amount of battery.
