Problems solved by technology

[0006] However, for mounting, it is inevitable to use additional parts, that is, washers and nuts, so the production cost of this type of head actuator arm combination will increase
Furthermore, the assembly process becomes complicated and time-consuming due to the use of additional parts in the assembly process

Embodiment Construction

[0024] now refer to Figure 2a-2b and Figure 3-4 , which describes in detail a preferred embodiment of the head actuator assembly of the present invention. refer to Figure 2a and Figure 2b , the head actuator assembly 202 includes the actuator arm 209, which is made of any suitable rigid material, such as stainless steel, so as to fully support the magnetic head 201 installed at one end thereof. The other end of the driving arm 209 is formed with a mounting hole 211 for fixing the driving arm 209 to other components (described later). The head actuator assembly 202 further includes a tail spacer 208 with a through hole 212 corresponding to the installation hole 211 of the actuator arm 209 . The drive arm 209 and fantail spacer 208 are fixed together by a pivot bearing assembly 207, which will be described in more detail below.

[0025] refer to Figure 3-4 , the pivot bearing assembly 207 is substantially cylindrical and includes an inner race 220 made of a rigid mate...

Abstract

The invention discloses a magnetic head drive arm combination, which comprises a pivot bearing component, a drive arm and a fantail space block. The pivot bearing component is provided with a main body which comprises a first end face, a second end face and a flange which is positioned between the first end face and the second end face and extends from the main body. The flange is provided with afirst boundary surface close to the first end face of the main body and a second boundary surface opposite to the first boundary surface. The drive arm is arranged on the main body and is fixed on the first boundary surface of the flange. The fantail space block is arranged on the main body and is fixed on the second interface of the flange. The magnetic head drive arm combination reduces additional components and has a simple structure and low manufacturing cost. The invention further discloses a magnetic disk drive unit using the magnetic head drive arm.

Description

technical field [0001] The present invention relates to an information recording device, in particular to a disk drive unit, and more particularly to a head stack assembly used in the disk drive unit. Background technique [0002] A disk drive unit is a known information storage device that utilizes a magnetic medium for storing data by selectively reading data from or writing to a rotating magnetic medium, such as a magnetic disk, using a movable read / write head positioned over the magnetic medium. Magnetic media writes data. [0003] Figure 1a A conventional disk drive unit 100 is illustrated showing a disk 104 mounted on and rotated by a spindle motor 105 . The head actuator assembly 102 carries the magnetic head 101 on which the read / write head is mounted. A voice-coil motor (voice-coil motor) 103 is used to control the movement of the magnetic head driving arm assembly 102, thereby controlling the movement of the magnetic head 101 between magnetic tracks on the surfa...
