Problems solved by technology

Corresponding to the reduction in wall thickness, the strength of the base is reduced
Therefore, in the case of a structure in which the collection filter is sandwiched, a load acts on the base, and the base may be deformed.

no. 1 Embodiment approach

[0015] As the disk device, the hard disk drive (HDD) of the first embodiment will be described in detail.

[0016] figure 1 It is an exploded perspective view of the HDD of the first embodiment shown with the top cover removed.

[0017] The HDD includes a flat, substantially rectangular housing 10 . The box body 10 has a rectangular box-shaped base 12 and a top cover 14 with an open upper surface. The base 12 has a rectangular bottom wall 12 a facing the top cover 14 with a gap therebetween, and side walls 12 b erected along the periphery of the bottom wall, and is integrally formed of, for example, aluminum. The top cover 14 is formed in a rectangular plate shape using, for example, stainless steel. The top cover 14 is screw-fastened (thread-stopped) on the side wall 12 b of the base 12 by a plurality of screw members 13 , and blocks the upper opening of the base 12 .

no. 2 Embodiment approach

[0046] Figure 4 It is a perspective view which shows the filter unit of the HDD of 2nd Embodiment.

[0047] As shown in the figure, according to the second embodiment, the filter unit 40 has a plate-shaped base 42 and a holding frame 44 which are integrally formed of synthetic resin or the like. The base 42 is attached to the inner surface of the box body 10 such as the inner surface of the top cover 14 .

[0048] The insertion port 51 b is opened on the upper surface and the front surface of the upper end portion of the main wall 51 , that is, the end portion on the opposite side to the base 42 . The insertion port 51b communicates with the internal space (storage portion) of the main wall 51 . Thereby, the filter main body 46 can be pulled out and inserted with respect to the internal space of the main wall 51 through the insertion opening 51b. That is, the filter body 46 can be attached to and detached from the holding frame 44 .

Abstract

The invention provides a disc apparatus, and the filter of the disc apparatus can be easily assembled or disassembled. The disk apparatus includes a casing, a rotatable disk recording medium that is disposed within the casing, a head configured to process information with respect to the recording medium, an actuator assembly that is disposed within the casing and that movably supports the head, and a filter unit (40) that is disposed within the casing. The filter unit (40) includes a base section (42) fixed to an inner surface of the casing, a holding frame (44) coupled to the base, and a collection filter (46) detachably held in place by the holding frame.

Description

[0001] This application enjoys the priority of the prior application with Japanese Patent Application No. 2018-52774 (filing date: March 20, 2018). This application incorporates the entire content of the earlier application by reference to this earlier application. technical field [0002] Embodiments of the present invention relate to disk devices. Background technique [0003] As a disk drive, for example, a hard disk drive (HDD) includes a magnetic disk arranged in a housing, a spindle motor that supports the magnetic disk and rotates it, an actuator unit that supports the magnetic head, and a voice coil motor that drives the actuator unit. As an example of a movable part. In addition, the HDD is equipped with a collection filter (circulation filter) that traps dust generated in the case by the operation of the movable part. An HDD using an electrostatic filter as a trapping filter has been proposed. [0004] Usually, the collection filter is installed in the box in a ...
