Embodiment Construction

[0040] Will now refer to Figure 1 to 9 The first embodiment of the present invention is described.

[0041] figure 1 The hard disk drive shown in (hereinafter referred to as "hard disk") includes a housing 2, a magnetic disk 4, a bracket 6, and a positioning motor 7. The magnetic disk 4 can rotate around the spindle 3. The bracket 6 can rotate around the pivot 5. The positioning motor 7 rotates the carriage 6. The housing 2 is covered by a cover (not shown).

[0042] figure 2 It is a cross-sectional view typically showing a part of the disk drive 1. Such as figure 2 As shown, the bracket 6 includes a plurality of (for example, three) actuating arms 8. Each suspension 10 is respectively mounted on the corresponding distal end portion of the actuating arm 8. A float 11 constituting a magnetic head is provided on the distal end of each suspension 10.

[0043] If the magnetic disk 4 rotates around the spindle 3 at a high speed, an air bearing is formed between the magnetic dis...

Abstract

A first conductor member (55) includes an amplifier-side first conductor (55a), a head-side first conductor (55b), and first and second interleaved conductors (61,62). A second conductor member (56) includes an amplifier-side second conductor (56a), a head-side second conductor (55b), and third and fourth interleave conductors (63,64). The second interleaved conductor (62) is connected to the amplifier-side first conductor (55a) through a first jumper conductor (91). The fourth interleave conductor (64) is connected to the head-side second conductor (56b) through a second jumper conductor (92). The jumper conductors (91,92) are formed by partially etching a metal base (50). The jumper conductors (91,92) are individually inclined at angles of 45 DEG or less to an axis (X) which extends in a wiring direction of each of the interleaved conductors (61-64).

Description

Background of the invention [0001] The present invention relates to a flexure used in a disk drive in an information processing device such as a personal computer. [0002] Hard disk drives (HDD) are used in information processing devices such as personal computers. The hard disk drive includes a disk that can rotate around a spindle, a bracket that can rotate around a pivot, and the like. The disk drive suspension is provided on the arm of the bracket. [0003] The disk drive suspension includes a base plate and a load beam. The flexure is positioned on the load beam. The floating block is mounted on a gimbal portion formed near the distal end of the flexure. The floating block is provided with a member (transducer) for accessing data, that is, reading or writing data. The suspension, flexure, etc. constitute the magnetic head gimbal assembly. [0004] The flexure is any of the various available types used according to the required specifications. A flexure with a conductor is...
