Description

[Detailed Description of the Invention] This invention relates to a magnetic disk storage device that records and reproduces information on a magnetic disk.

First, the reading and reproducing mechanism section of a conventional magnetic disk storage device will be explained with reference to FIGS. 1 and 2.

In the figure, reference numeral 1 denotes a magnetic disk for storing information, which is positioned and fixed by a spindle cone 2 and rotated at a constant rotational speed.

A bridge 3 holds a magnet 4, which will be described later, and protects the magnetic disk 1.

Numeral 4 is a magnet that brings the pad 5 held by the pad arm 6 into contact with the magnetic disk 1 when recording or reproducing information on the magnetic disk 1, and pulls up the pad 5 from the magnetic disk 1 when not recording or reproducing information. .

A carriage 7 is provided facing the pad 5 and holds a magnetic head 8 for recording and reproducing information on the magnetic disk, and a pad arm 6 for holding the pad 5. This carriage is driven by a stepping motor 9 and a lead screw 10. and placed on any magnetic disk.

Note that P is a pin. Since the above conventional arrangement is as described above, when recording and reproducing information, the magnetic disk 1 is interposed between the magnetic head 8 and the pad 5, and pressure is applied by the pad arm 6.

On the other hand, when information is not being recorded or reproduced, the pad arm 6 is pulled up by the magnet 4 and the pad 5 is placed on the magnetic disk 1.
There will be no contact.

In the above-mentioned recording and reproducing mechanism, if the pad that brings the magnetic disk into contact with the magnetic head is not pressed against the magnetic head and the magnetic disk at an accurate position, a satisfactory recording and reproducing function will not be obtained, and the pad itself will wear unevenly. As time passes, the recording and reproducing functions deteriorate and the lifespan of the magnetic disk and magnetic head is also shortened.

Conventionally, in this type of device, the pad that presses the magnetic disk against the magnetic head is fixed to a pad arm that holds the pad, making it difficult to adjust the position satisfactorily.
In order to accurately position the magnetic head with respect to the magnetic head, the precision of the pad arm that holds the pad must be improved, which increases the unit cost of parts.

Furthermore, this pad wears out and needs to be replaced at an appropriate time, but it is not easy to replace it because the pad arm integrated with the pad and the like must be replaced.

This invention was made to solve these drawbacks, and its features are that the pad is detachably attached to the pad arm and that the relative relationship with the magnetic head can be adjusted.

An embodiment of this invention will be described below with reference to FIGS. 3 and 4.

In Figures 3 and 4, 1. 2. 5. 6゜7, 8. 9.10. P is the same as in FIGS. 1 and 2.

Reference numeral 11 indicates a pad block to which the pad 5 is attached, and reference numeral 12 indicates a mounting screw for detachably mounting the pad block 11 to the pad arm 6 through a mounting hole larger than an ordinary tapped hole.

Further, the position of the pad block 11 can be adjusted in the direction perpendicular to the plane of the paper and in the left and right directions by adjusting the mounting screws.

Note that the above-mentioned horizontal direction and horizontal direction are for adjusting the position of the pad with respect to the magnetic head in a direction parallel to the disk.

In this idea, the pad 5 is separated from the pad arm 6,
Since the pad block 11 integrated with the pad 5 is fixed to the pad arm 6 with the mounting screw 12, the mounting screw 1
By loosening 2, the position relative to the magnetic head 8 can be easily adjusted.

In addition, when performing maintenance and replacement, in conventional devices, it is necessary to remove the pin P etc. from the carriage 7 and replace the pad arm 6 itself, but with this invention, as shown in Figs. 3 and 4, all that is required is to remove the mounting screw 12. Therefore, the pad 5 can be easily replaced.

As explained above, according to this invention, it is easier to adjust the mounting position of the pad 5 in the direction parallel to the disk with respect to the magnetic head 8 compared to the conventional device, and the accurate mounting position of the pad 5 allows recording and reproducing functions. This has advantages such as increasing the life of the magnetic head 8 and magnetic disk 1, and making maintenance inspection and replacement of the pad 5 easy.
