Embodiment Construction

[0047] Hereinafter, various embodiments of the present invention will be described with reference to the accompanying drawings, in which the same reference numerals in the various drawings represent the same elements. As described above, the present invention provides a cantilever for a magnetic head flap assembly of a disk drive unit. The cantilever includes a vibration sensor. The vibration sensor includes a base and is formed in the base for supporting installation. The load part of the magnetic head thereon, and at least two connecting arms connecting the base part and the load part. By mounting the vibration sensor with lower rigidity on the cantilever tongue and sandwiching it between the cantilever tongue and the magnetic head, it is more sensitive to the vibration of the magnetic head, thereby improving the read and write performance of the magnetic head and the entire disk The performance of the drive unit.

Abstract

The invention discloses a vibrating sensor used for a magnetic head, which comprises a base, a loading part and at least two connecting arms, wherein the loading part is formed in the base and is used for supporting the magnetic head thereon; and the connecting arms are used for connecting the base and the loading part. The vibrating sensor can agilely sense the vibration of the magnetic head, thereby keeping the flight altitude and improving the property of the magnetic head. The invention also discloses a combination of a cantilever part and a magnetic head folding sheet with the vibrating sensor, a manufacturing method thereof, and a disk driving unit.

Description

Technical field [0001] The present invention relates to an information recording disk drive unit, in particular to a vibration sensor for inducing the vibration of a magnetic head, a cantilever with the sensor, a magnetic head flap assembly and a manufacturing method thereof, and a disk drive unit. Background technique [0002] Disk drive unit is a common information storage device. figure 1 Shown is a conventional disk drive unit that includes a typical drive arm 104 for writing to and reading data from the disk 101. Typically, a voice-coil motor (Voice-Coil Motor, VCM) controls the movement of the driving arm 104. A cantilever 105 is mounted on the top of the driving arm 104, and the cantilever 105 supports a magnetic head 103 with a read-write head (not shown). When the disk drive unit is operating, the spindle motor 102 rotates the disk 101 at a high speed, and the air pressure generated by the rotation of the disk 103 causes the head 103 to fly above the disk 101. The magn...
