Embodiment Construction

[0022] As described above, a head drop prevention system of the present invention is used to reduce the movement of the magnetic head when an acceleration is applied to the head suspension assembly, thereby preventing the magnetic head on the suspension from vibrating strongly and hitting the disk surface, thereby making the head suspension assembly have good performance. seismic performance. More importantly, the head drop prevention system of the present invention has a simple structure and is easy to manufacture and assemble. Several embodiments of the combination of the magnetic head drop preventing system and the magnetic head suspension of the present invention are introduced below.

[0023] refer to figure 1 , according to one embodiment of the present invention, a head arm assembly 13 (head arm assembly, HAA) (head arm assembly with only one head gimbal assembly) includes a magnetic head 203, a suspension member 14 for carrying the magnetic head 203, and a suspension ...

Abstract

The related magnetic head fall preventing system for HAS comprises: a load to reduce head motion, and a weight holder connected and on the reverse surface of HAS suspension member. This invention also discloses the disk drive unit.

Description

technical field [0001] The invention relates to a head stack assembly (head stack assembly, HSA) and a disk drive unit, in particular to a magnetic head drop prevention system used in the head stack assembly and capable of achieving good anti-vibration performance. Background technique [0002] A disk drive is an information storage device that uses magnetic media to store data. A typical existing disk drive unit includes a disk and a head suspension assembly (HSA). Wherein, the magnetic disk is mounted on a spindle motor for driving the magnetic disk to rotate. The magnetic head on the magnetic head suspension assembly flies over the surface of the disk, and then reads or writes data from the disk. [0003] The existing head suspension assembly includes a rigid driving arm, at least one flexible suspension fixed to one end of the driving arm, and a magnetic head mounted on the top of each suspension (the suspension with the magnetic head is called "head gimbal assembly") ...
