Abstract

PURPOSE:To prevent load from being changed to the medium of a magnetic head by the speed of loading the medium by fitting a spring board while inclin ing it so as to get a prescribed angle under the recording face of the recording medium. CONSTITUTION:A medium 8 is held by a magnetic head 1 and a magnetic head 1a opposed to this head 1 therebetween, and pressing load is generated through a magnetic head supporting body 2 by a spring board 4 fitted while being inclined so as to get an angle theta under the horizontal face of the medium. Therefore, it is not necessary to generate the load for pressing the magnetic head to the medium by using a torsion soil spring or a compressing spring, and since friction is not generated at the contact point between the torsion soil spring and the magnetic head to the supporting body, the load is not changed in the case of pulling up and down the magnetic head supporting body. Thus, there is no problem that the load is changed for pressing the magnetic head to the medium 8 by the speed of loading the medium 8.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic head support device for supporting a magnetic head used in a magnetic tisf device.

[Conventional technology]

As shown in FIG. 4, a conventional magnetic head support device for supporting a magnetic head used in a magnetic disk device has a magnetic spatula 1 or 21 mm at its tip. The spring plate 14 fixedly supports the magnetic head support 12 or 22 at the front end thereof, or the two opposing magnetic heads 11 and 1lat or 21 and 21.
A position parallel (0°) to the medium 8 (or the lower magnetic spatula 1 to 1.1 a or 2 ], the sliding surface of a) which is installed between the media 8 and ready for recording or reproduction. However, it does not have the function of generating a load to press the magnetic spatulas 1 to 11 or 21 against the medium 8.

For this purpose, a torsion coil spring 10 or a compression coil spring 11 is used, and thereby the magnetic spatula 1 to ]1 or 21
A load is generated to press the material against the medium.

[Problems to be Solved by the Invention] As mentioned above, the conventional magnetic spatula I/support device has a spring plate that fixes and supports the magnetic spatula to support at the air end, or Since the magnetic head is in a parallel position, it does not have the effect of generating a load to press the magnetic head against the medium, and a torsion coil spring or compression coil spring is required to provide that effect. It is said that This increase in number of parts is an obstacle to cost reduction. In addition, when using a torsion coil spring, friction is generated at the contact point (pressure point) between the torsion coil spring and the magnetic head support, so the magnetic head support is pulled twice as fast. A drawback is that the load sometimes changes, and the load for pressing the magnetic spatula I against the medium changes depending on the speed of loading the medium.

[Means to solve the problem]

A magnetic head support device of the present invention includes a magnetic spatula 1- for recording or reproducing information on a recording medium, a magnetic head support for holding the magnetic head at a tip end, and a magnetic head support for holding the magnetic head at a front end. In a magnetic spatula I/support device, the magnetic spatula I/support device includes a spring plate that is fixedly supported and fixed to a support column at a rear end, the spring plate being tilted downward at a predetermined angle with respect to the recording surface of the recording medium. It is attached to the support column at an angle so as to have the same shape.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a side view showing an embodiment of the present invention.

In FIG. 1, 1 is a magnetic head, 2 is a support for a magnetic head which holds the magnetic head at its tip, 3 is a magnetic shield attached to the magnetic head support 2, and 4 is a magnetic head support.
has a spring plate that fixes and supports the magnetic head support 2 at its front end, has a specific spring constant 1, and is installed at an angle θ downward with respect to the horizontal plane. 5 is a support column that supports the rear end of the splash plate 4.

FIG. 2 is a side view showing a state in which the medium 8 is held between the magnetic head 1 and the magnetic head 1a facing the magnetic head 1 and the spring plate 4. 7g is shown in which a pressing load is generated on the magnetic pole 1 via the support 2. In the figure, 6 is a cymbal spring, and 7 is a movable member.

3(a> and (1)) are side views showing two different states of the splash plate 4 in the state shown in FIG. 2.

The example in FIG. 3(a) is an example in which the spring plate 4 (4a) is attached to the support column 5 at an angle θ, and the example in FIG. 4 (41)) is attached horizontally to the support column 5 inside, and is bent at an angle θ outside the support column 5.

Finally, the spring plate 4 is set so as to have an angle θ with respect to the support column 5. The spring constant of the spring plate 4 is determined by design from the length and thickness T.

〔Effect of the invention〕

As explained above, the magnetic head support device of the present invention has
By attaching the spring plate that fixedly supports the magnetic head support at the front end at a predetermined angle downward with respect to the recording surface of the recording medium, it is possible to use a torsion coil spring or a compression spring as in the past. There is no need to use a coil spring to generate a load to press the magnetic nod against the medium, and therefore the number of parts can be reduced and the cost can be reduced. In addition, since there is no friction at the contact point (pressure point) between the torsion coil spring and the magnetic head support, the load does not change when the magnetic throat support is pulled up or down, and the media This has the effect of solving the problem that the load for pressing the magnetic head against the medium changes depending on the mounting speed. Furthermore, the load for pressing the magnetic head against the medium is determined by the spring constant, length, and thickness of the spring plate, so the load value can be set to the desired value by setting each of these to appropriate values. Since it is possible to obtain a stable load by controlling each tolerance, there is also the effect that the contact state between the magnetic head and the medium can be made stable.
