回路は回路基板１３．１４ Ｋ塔載されている。The disk 3 that stores information is the spindle motor hub 2a
) (It is fixed and rotates. The head 4, which transfers information to the disk 3, is aerodynamically floating above the surface of the disk 3 with a small gap.In order to maintain a stable flying posture of the head, there is no external space inside the disk chamber. A gasket 12 is inserted between the cover 5 and the base 10 to seal the space to prevent dirty air from entering, and the airflow 7 generated by the rotational force of the disk 3 is purified through a dust removal filter 6. The head 4 writes data in a plurality of concentric circles onto the disk 3 using a voice coil motor 15.
Seek as shown in 7 and position accurately. Circuits for controlling the rotation of the disk 30, controlling the voice fill motor 15, writing and reading data, and interface with host devices are mounted on a 13.14K circuit board.

するものには例えば米国特許第４３６７５０２号、同４
３２３９３９号等が挙げられる。The disk size used has increased as recording density has increased.
The diameter decreased from 14 inches to 8 inches to 5 inches,
Since the disk rotation energy can be reduced, demand is increasing rapidly. Furthermore, the height of the device is required to be small in order to incorporate it into a tabletop or portable humpeater system. Efforts have been made to reduce the size by integrating circuit board elements, but the increase in recording density requires a compensation circuit, and the disadvantage is that the height cannot be reduced by using two circuit boards. Ta. Related devices of this type include, for example, U.S. Pat. Nos. 4,367,502 and 4.
No. 323939, etc. may be mentioned.
本発明の目的は装置高さ寸法の小さいディスク装置を提
供することにある。An object of the present invention is to provide a disk device with a small device height.
本発明は、ディスクとディスクの間に回路基板を収納し
、装置高さを小さくするものである。The present invention reduces the height of the device by storing a circuit board between the disks.
以下本発明の実施例を第１図、第２図、第３図を用いて
説明する。Embodiments of the present invention will be described below with reference to FIGS. 1, 2, and 3.

間であるがヘッド４の所以外は使用されていない。Base 1)c Disks 3 are spaced apart from each other by disk spacers 16 on the spindle hub 2a of the installed spindle motor 2. The head 4 that records information on the disk 3 is moved in the rectangular direction 1 by a voice coil motor 15.
Seek the disk surface as shown in step 7. The space between the disks 3 is a space necessary for the head 4 to move, but the space other than the head 4 is not used.

にて取りうける。A circuit board 8 hollowed out so as not to touch the disk spacer 161Cm is placed in this space, and signals are connected to the head 4 through a cable 11, and signals to the main panel 18 are connected through a cable 10. To prevent the circuit board 8 from coming into contact with the disk 3, screws 9 are inserted into the protrusion 19 from the base 1.

来るので装置高さ寸法縮少の効果がある。According to the present invention, the distance between the head 4 and the circuit board 8 can be shortened, the length of the cable 11 for the minute voltage signal is short, and the base 1
Since the circuit board 8 is located inside the cover 5, it is resistant to electrical noise from the outside. Also, external circuit board 18
Since the disk 3 can also be mounted between another disk 3, the height of the device can be reduced.
