CONSTITUTION:A pattern is formed on an airtight retention cover 9 of a disk device and electronic circuit parts 10 for controlling a device are mounted. Also, a spindle motor 3 and a connector 12 for making connection to a FPC 7 are provide at an airtight retention cover 9 and the connector 12 is connected by mounting the cover 9 onto a base 8, thus eliminating the need for a plug-in substrate and achieving miniaturization by dimensions A which can be used for HDA for improved device volume ratio of HDA and a compact and large- volume disk device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for mounting electronic circuit components in a disk device, and particularly to a method for increasing the device capacity of an HDA by reducing the space of a PCB.

[Conventional technology]

Conventional disk devices have a dedicated plug-in board on which electronic circuit components are mounted, as described in Jikai 63-127482, and have a structure in which this plug-in board is attached to the disk device.

[Problem to be solved by the invention]

In the above conventional technology, the electronic circuit components were mounted on a dedicated plug-in board and then attached to the disk device. Therefore, in the case of a small magnetic disk device that requires size interchangeability with a floppy disk device, This has caused a problem in that it hinders efforts to increase capacity given the fixed size limitations.

An object of the present invention is to eliminate the problems caused by the prior art, and to provide a compact and large-capacity disk device.

[Means to solve the problem]

In order to achieve the above object, the disk device according to the present invention has the following features:
It is characterized by mounting electronic circuit components on the airtight cover.

[Effect]

By mounting the electronic circuit components on the airtight cover, the disk device having the above characteristics can improve the device volumetric ratio of the HDA with the same external dimensions as the conventional disk device.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail using the drawings. FIG. 1 is a side view of a disk device according to the present invention. FIG. 2 is a side view of a disk device in the conventional invention.

First, the configuration of the disk device 1 includes a magnetic recording disk 2 for magnetically recording data, a spindle motor 3 for rotating the magnetic recording disk at a constant speed, and a magnetic recording disk 2 for reading/writing data. A magnetic head 4, a carriage 5 for supporting the magnetic head 4, an actuator 6 for driving the carriage 5 and positioning the magnetic head 4 on the magnetic recording disk 2 for data writing/writing, and the magnetic head 4.
It consists of an FPC 7 for transmitting signals from to the circuit section, a base 8 that supports these mechanisms, and an airtight cover 9 that hermetically covers the mechanisms on the base 8.

In addition to the configuration of the disk device described above, the conventional disk device includes a plug-in board 1 on the bottom surface of the disk device 1, on which electronic circuit components 10 for controlling the device are mounted, as shown in FIG.
1 was installed.

On the other hand, in the disk device according to the embodiment of the present invention, as shown in FIG. 1, a pattern is formed on the airtight cover 9, and an electronic circuit component 10 for controlling the device is mounted. The airtight cover also includes the spindle motor 3.
and a connector 12 for connection to the FPC 7, and by attaching the airtight cover 9 to the base 8, the connectors 12 can be connected to each other.

As described above, according to the present embodiment, as shown in FIG. 1, there is more margin than the conventional disk device by dimension A.

Therefore, when there are size restrictions such as in small disk devices, the size of the disk can be used for the HDA, making it possible to improve the device volume ratio of the HDA with the same external dimensions as conventional disk devices. This has the effect that it is possible to achieve smaller size and larger capacity.

〔Effect of the invention〕

According to the present invention, since the electronic circuit components are mounted on the airtight cover, there is no need for a plug-in board, and in a small magnetic disk device with a particularly determined size limit, the HDA can be installed with the same external dimensions as the conventional one. Since it is possible to improve the device volume ratio of the disk device, there is an effect that the disk device can be made smaller and larger in capacity.
