Abstract

PURPOSE:To make the magnetic head small and to improve the reliability of the mechanism by providing plural signal wire leadout parts opposite to a floating face, plural separated supports from each signal lead wire leadout part having both a magnetic head support function and a conduction function and a reinforcement member between the supports. CONSTITUTION:Plural signal lead wires from a magnetic head 1 are led opposite to a floating face of the magnetic head 1 and plural supports 4 having both a conduction function and a magnetic head support function are directly soldered to the signal wire leadout part 2.

Thus, the magnetic head is formed small, the OSS resistance is improved, the reliability of the mechanism is improved, the access time is reduced, the distance between media is decreased and then the device employing the mechanism is made small.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic disk device, and particularly to a magnetic head support mechanism thereof.

[Conventional technology]

Magnetic disk drives record large amounts of information and play a central role in the file memory of information processing systems and computer systems as memories that can be randomly accessed.The main performances of magnetic disk drives are areal recording density and average access time ( The aSS resistance performance is evaluated in terms of the time required to position the magnetic head on a predetermined track) and device reliability. The average access time can be reduced in proportion to the square root of the moving part mass. Further, one of the factors for improving the anti-aSS performance is miniaturization of the magnetic head. That is, by making the magnetic head smaller, the damage to the medium can be reduced.

FIG. 2 is a side view of a conventional thin film type floating magnetic head device disclosed in, for example, Journal of the Japan Society of Mechanical Engineers, Vol. 8'7, No. 791, October 1980. Further, FIG. 3 is a perspective view showing the relationship between the signal extraction method and suspension of a conventional floating magnetic head.

In the figure, (1) is a magnetic head, (2) is a signal line extraction part, (5) is a suspension that supports the magnetic head, (7) is a lead wire, (6) is a tube for passing the lead wire (7), (8) is a magnetic recording medium that rotates and travels in the direction of the arrow (&).

The conventional magnetic head device is configured as described above, and when the magnetic recording medium (8) rotates at a constant speed, the magnetic head (1
) An air flow (b) is generated on the lower surface, and a pushing force similar to that of a flying object is applied to the magnetic head (1).

The signal line is generally pulled out from the side of the magnetic head (1), and the signal is connected to the suspension (5) through a tube (
6) is attached, and the lead wire (7) is used for transmission.

In addition, as mentioned above, in magnetic disk devices, the size of the magnetic head is being reduced in order to improve reliability (improve anti-ASS performance), shorten access time, and downsize the device. Problem] In the conventional magnetic head device as described above,
When trying to make the magnetic head smaller in order to improve S performance, shorten access time, and downsize the device, the suspension that supports the magnetic head is complicated, and the upper surface of the magnetic head (the surface opposite to the floating surface) has a certain amount of space. area must be secured. Furthermore, since the upper surface is covered by the suspension, the signal lines must be drawn out from the side surface of the magnetic head, so the side surface cannot be made smaller. Therefore, there is a problem in that there is a limit to the miniaturization of the magnetic head.

Further, in the conventional magnetic head support mechanism, lead wires are used from the magnetic head to the arm for signal transmission, and there is a problem in that the process of attaching the lead wires and connecting the lead wires takes time.

This invention was made to solve the above-mentioned problems, and allows the magnetic head to be made smaller and improves the reliability of the device (resistance to a
The objective is to obtain a magnetic head support mechanism that can improve SS performance), shorten access time, and downsize the device, as well as eliminate lead wires and shorten head assembly time. ] The magnetic head support mechanism according to the present invention is provided with a plurality of signal line lead-out parts on the side opposite to the air bearing surface, and from each of the signal line lead-out parts there is provided a separate magnetic head support mechanism having both a magnetic head support function and a conductive function. A plurality of supports are provided, and a reinforcing material is provided between the supports.

[Effect]

The magnetic head support mechanism according to the present invention has both the function of supporting a magnetic head and the function of conducting electricity. [Embodiment] FIG. 1 is a plan view showing an embodiment of the present invention. In the figure, (1) is a magnetic head, (2) is a signal line lead-out portion, (3) is a reinforcing material, and (4) is a support body.

Signals are extracted from the magnetic head (1) using the magnetic head (1).
1) Pull it out to the side opposite to the floating surface. A support (4) having both a conductive function and a magnetic head support function is directly soldered to the signal line lead-out part (2).

Since the structure of the support body (4) for drawing out the signal line and supporting the magnetic head is simple, it is possible to draw out the signal and support the magnetic head in a small space on the upper surface (opposite the floating surface) of the magnetic head (1). I can do it. Therefore, the magnetic head (1
) can be made small. Further, there is no need to provide a signal line lead-out portion on the side surface of the magnetic head, and the magnetic head (1) can be made thin.

Since the supports (4) of the magnetic head are separated from each other depending on the number of signal lines, a reinforcing material (3) is provided between the supports. The shapes of the support body (4) and the reinforcing material (3) are not particularly limited to those shown in the figures of the above embodiments.

The magnetic head support (4) and the arm are connected by screws,
Soldering is done with etc. Therefore, the signal output from the magnetic head (4) is carried out by the support (4) itself up to the arm, and no lead wire is required.

Although the above embodiment shows an example of two supports, a plurality of supports (4) may be provided depending on the number of signal lines.

〔Effect of the invention〕

As described above, according to the present invention, a magnetic head is provided with a plurality of signal line lead-out parts on the side opposite to the air bearing surface, and each signal line lead-out part of the magnetic head has both a magnetic head support function and a conductive function. By providing a plurality of separate supports with a magnetic head and providing a reinforcing material between the supports, the magnetic head can be made smaller. The miniaturization of magnetic heads has the following effects. (1) The aSS resistance performance is improved and the reliability of the device is improved. (2) Access time can be shortened.

(3) The distance between the media can be shortened and the device can be made smaller. In addition, (4) the signal is transmitted by the support itself, and the connection between the support and the magnetic head and arm can be done by soldering or screwing, so lead wires are not required, and lead wire installation, connection, etc. This process can be omitted and the process can be simplified.
