本発明は、例えば磁気ディスク装置の如きディスク記憶
装置に係り、特に小形化するのに有利な、ヘッドを取付
けるヘッドアームの構造を改良したものに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a disk storage device such as a magnetic disk device, and particularly to an improved structure of a head arm to which a head is attached, which is advantageous for downsizing. .
近年、Ｓ気ディ２り装置の大容量化は言うまでもなく、

In particular, market demands for smaller equipment and higher throughput are becoming increasingly strong. In order to meet this demand, with the improvement of information recording density, the miniaturization and weight reduction of the actuator section for the mother air vent has become an important issue.In other words, if the actuator section is made smaller, the head disk The assembly (hereinafter referred to as HDA) can also be made smaller, and the entire device can be made more compact.Furthermore, the lighter weight of the actuator contributes to faster movement speed, which shortens the time it takes to move to the target track, resulting in higher nulls. - It is advantageous for putting

による。In order to make the actuator smaller and lighter, it is important to reduce the size and weight of the magnetic head assembly mounted on the actuator. In other words, when the mass of the magnetic head assembly is reduced, the force generated by the actuator for driving the dough is also reduced, and as a result, a compact actuator section can be realized. Furthermore, in order to miniaturize the HDA, it is important to determine how small the mounting interval between multiple magnetic disk plates can be made, and this depends on how thin the head arm that connects the magnetic head assembly and actuator can be designed. It depends on whether you can do it.

ッドアーム薄形化のためにはこのＬＳＩの小形化も重要
である。Conventionally, the limit on the thickness of this head arm has been determined by the thickness of the LSI for read/write amplifiers mounted thereon, and in order to make the head arm thinner, it is also important to miniaturize this LSI.
従来例を第３１図に従い詳細に説明する。A conventional example will be explained in detail with reference to FIG.

ッド１が配置されている。A plurality of mountain disks 2 are rotated by a spindle (not shown), and one S air head 1 is arranged on each 2 surface of each six air disk.

The load arm 3 is mounted on the tip of the keel with a screw 5, and the other end is connected to the carriage with a screw 10.

An SI 7 and an F'PC (flexible pattern cable) 15 for mounting the SI 7 are installed. The information signal is fixed to the carriage 11 by the plate 16.
4. The FP on the load arm 6 (, '15° LSI 7 for read/write. Transmitted to the node 1 to the mountain via the lead wire 4, and writes the daily information to the mountain disk 2 (

が重要である。The loading platform for reading (reading) is the reverse of this. The carriage 11 is connected to a voice coil motor and a nutep motor, and moves and stops at high speed, making it difficult to position the air head 1.As is clear from the above explanation, the thickness of the head arm assembly 6 The dimensions are determined by the thickness and mounting dimensions of the read/write LSI 7.
In addition to downsizing, it is important to consider how to implement it compactly.

It is disclosed by No. 1.
しかし、本例は実用面について十分考慮さねていない。However, this example does not give sufficient consideration to practical aspects.
