Problems solved by technology

During the assembly process, due to the limitation of the installation space, it is difficult to ensure the position assembly accuracy of the magnetic head and / or piezoelectric element in this side installation method, and the installation process is complicated
[0013] In addition, in the structural design of the traditional microdrive, since the magnetic head 103 is limited by the U-shaped frame of the microdrive 105 and one end is fixed, it is impossible to realize large head position adjustment.

Embodiment Construction

[0076] Several embodiments of the microactuator of the present invention are now described. It should be noted that the microdrive can be applied to any disk drive device having a microdrive, and is not limited to the specific structure shown in the drawings. That is, the present invention is applicable to any suitable microdrive-containing device in any field.

[0077] Fig. 3a-7b has shown the microdrive described in an embodiment of the present invention, wherein, Fig. 3a-3c have shown the state that this microdrive is installed on a magnetic head gimbal assembly, and Fig. 3d has shown the magnetic head gimbal shown in Fig. 3a A partial perspective view of the cantilever of the sheet assembly. As shown in the figure, the HGA 200 includes a piezoelectric micro-actuator 205 , a magnetic head 203 mounted on the piezoelectric micro-actuator 205 , and a suspension member 213 for supporting the piezoelectric micro-actuator 205 and the magnetic head 203 .

[0078] The suspension ...

Abstract

The invention discloses a micro-driver of head tabs composition, which comprises the following parts: at least one piezoelectric element, connecting arm to support the piezoelectric element, micro-driver assembling part at one end of the connecting arm, head assembling part to connect the other end of the connecting arm or piezoelectric element, wherein the breadth of piezoelectric element is more than the breadth of the connecting arm; the piezoelectric element can be excited to guide selective movement of connecting arm. The invention also provides a head tabs combination and disc driving unit with micro-driver.

Description

technical field [0001] The present invention relates to an information recording disk drive unit, and more particularly to a microdrive, including a head gimbal assembly (HGA) and a disk drive unit of the microdrive. Background technique [0002] A common type of information storage device is a magnetic disk drive system that uses magnetic media to store data and a moveable read / write head positioned over the magnetic media to selectively read data from and write data to the magnetic media superior. [0003] Consumers have always expected increasing storage capacity from such disk drive systems, while at the same time expecting faster and more accurate read and write speeds. Therefore, disk manufacturers have been devoting themselves to developing disk systems with higher storage capacity, such as increasing the density of magnetic tracks by reducing the track width or track spacing on the disk, thereby indirectly increasing the storage capacity of the disk. However, as th...
