Abstract

PURPOSE:To miniaturize a cartridge, by forming cuts through a part of a short side together with the side plate of a cartridge case in addition to a hole through which the revolving power is transmitted to a disk contained in the cartridge case constituted by providing successively two rectangular side plates and therefore inserting a magnetic head to the cartridge case. CONSTITUTION:A cartridge case 6 is formed by providing successively two rectangular flat plates 6a and 6b at 4 sides by means of a side plate 6c. An opening part 6d is formed to plates 6a and 6b to transmit the revolving power to a disk contained in the case 6, and a hub 2 is rotatably supported. Then a center hole 2a is drilled to the hub 2. The rotary shaft of a driver interlocks the hole 2a. At the same time, cut parts 6e-6g are provided to a side of the case 6. These cuts cover the plates 6a, 6b and 6c respectively. Thus a magnetic head can be loaded to and unloaded from the case 6 from an arrow A. As a result, it is just required to secure a slight distance for the magnetic head which touches both sides of the disk. This can reduce the thickness of the device.

ス３は第１の＋根３ａ。A flexible magnetic disk device is a type of external storage device for computers, and the storage medium of this device, the flexible magnetic disk, is a thin disc-shaped recording medium protected by a square flexible jacket. Another type is a flexible magnetic disk cart in which the central part of a disc-shaped recording medium is held by a hub, and the disc-shaped recording medium is rotatably housed in a flat-type cartridge case instead of a flexible jacket. Figure 1 shows a perspective view of such a conventional cartridge.
FIG. 3 I'
FIG. 2 is a side sectional view showing the cartridge shown in FIG. 1 being ejected from the disk-shaped recording medium drive device; Figure 11 of them
1. A hub 2 having a center hole 2a is coupled to the center of the disc-shaped recording medium 1. The cartridge case 3 is the first positive root 3a.

and a second opening 3e, and a first opening 3d' and a third opening 3f are provided in the second top plate 3b. The cartridge 4 is configured as described above. JNote,
- The first openings 3d and 3d' are for allowing insertion of the rotary shaft 5a for rotationally driving the disc-shaped recording medium 1 and the hub 2, and the second openings 3e and 3
The opening 3f is for allowing insertion of a head 5d for recording 1 or reproduction.

The hub 2 is engaged with the rotating shaft 5a through the hub 2, and the end surface of the hub 2 is engaged with the upper end of the rotor 5b. In fact, the two heads 5d are in contact with both surfaces of the disc-shaped recording medium 10 through the second opening 3e and the third opening 3f.

As shown in FIG. 3, the length l of the protruding portion of the rotary shaft 5a and the distance m that does not contact the cartridge case 3 must be avoided. That is, the two heads 5dK require a retraction space n. For this reason, it is necessary to provide a sufficient space in the disc-shaped recording medium 1 driving device 5 for retracting the head 5d, and the thickness of the disc-shaped recording medium 1 driving device 5 becomes thick.
