Cantilever member and manufacturing method thereof, magnetic head tab combination and disk drive unit

Abstract

The invention discloses a cantilever part used for supporting a magnetic head sliding block. The cantilever part comprises a flexible part, a compound circuit arranged on the flexible part, a front connecting contact and a back connecting contact of the flexible part. The front connecting contact of the flexible part is arranged on a position of the flexible part corresponding to the front side of the magnetic head sliding block, and the front connecting contact is connected with one circuit. The back connecting contact of the flexible part is arranged on a position of the flexible part corresponding to the tail side of the magnetic head sliding block and is connected with one circuit. The front and back connecting contacts of the flexible part can be integrated for forming together with the circuit and can be simultaneously arranged on the flexible part so as to simplify the manufacturing process and avoid correcting of connecting positions, thus guaranteeing the connecting force and connection position between the magnetic head sliding block and the cantilever part are not changed to further guarantee better state of the sliding block of the magnetic head. The invention simultaneously discloses a magnetic head sheet unit provided with the cantilever part, a magnetic head driving unit and a manufacturing method for the cantilever part.

Description

technical field [0001] The present invention relates to an information recording disk drive unit and its constituent elements, in particular to a suspension that connects a magnetic head slider in a single manner, a magnetic head flap assembly and a disk drive with the suspension, and also relates to the process for manufacturing the suspension method. Background technique [0002] A disk drive system is an information storage device that uses magnetic media to store data and selectively reads data from or writes data to the magnetic media with a movable read / write head positioned over the magnetic media superior. [0003] Referring to FIG. 1 , a disk drive typically includes several disks 6 connected to a spindle motor for rotation. A corresponding HGA comprising a head gimbal assembly (HGA) 1 is suspended on the surface of the magnetic disk 6 . The HGA 1 is connected and installed on the driving arm 4 . A voice coil motor (VCM) 5 is connected to the driving arm 4 to co...

Problems solved by technology

However, in this connection method, when the flexible member 40 is connected to the magnetic head slider 2 at the corresponding front position of the flexible member, it is necessary to additionally provide connection contacts 41, 41 ′ at the corresponding front position of the flexible member. The connection contacts 41, 41' on the front side of the part are independently manufactured with the trace pattern 43 and the connection contacts 42A-42D, and the connection contacts 41, 41' are placed on the flexible part 40 by optical processing (photo process) When it is connected, the slight positional alignment error of the connection contacts 41 and 41' will cause a large change in the connection force, and cause the static pitch attitude (PSA, pitch static attitude) and static roll attitude (RSA, RSA, roll static attitude) changes due to changes in the connection position, and accordingly, changes in pitch and roll attitudes will cause changes in the flying height of the magnetic head, which weakens the flying performance of the magnetic head and data read and write performance
