ツジにおいて、キズが発生しやすくなる。 As shown in FIG. 1, the conventional head support mechanism includes a support member (pivot) 14 that presses the head 2 with a vertical load, which is equipped with a read/write gap in the center for magnetically writing and reading electrical signal information.
is located on the back side of the surface where the flexible disk 1 and the head 2 come into contact, and the head 2 is structured to freely follow the surface of the flexible disk by means of a spring member 3. At this time, there is a read/write gap in the support member 14 on the back side of the head (2-1
) Support point 3-11 at the top of the center of the head width
It is located in Therefore, when the flexible disk 1 runs, a force that drags the flexible disk 1 parallel to the running surface in the direction of arrow A is generated due to friction, and a counterclockwise moment is generated in the head 2. For this reason, the contact surface of head 2
The distributed load moves in the direction opposite to arrow A, and the running condition tends to become unstable. Furthermore, scratches are likely to occur at the front edge of the head 2.

Another object of the present invention is to provide a head support mechanism that maintains a contact state in which running scratches are less likely to occur. The following description will be made based on examples.

支持機構を提供することができる。 The relationship between the forces acting in FIG. 2 of the present invention is shown in FIG. 4. A composite vector 7 of the vertical load 5 pressing the head 2 and the horizontal force 6 due to friction is applied to the contact surface 3-41 of the support member 44 and the center portion 2-1 of the head.
By being located on the line connecting the flexible disk 1, the flexible disk 1 has the effect of pressing against the center of the head when traveling. Based on the relationship between the head thickness and the coefficient of friction, there is an optimal deviation position within the range of 0.1 to 1.5 mm. For this reason, the surface pressure distribution near the central part 2-1 of the head where the read/write gap is present becomes large, stable head touch is obtained, and the head 2
Since no counterclockwise moment is generated, it is easy to follow the flexible disk 1. Therefore, it is possible to provide a head support mechanism that is more effective than the conventional one in that abnormal vibrations are less likely to occur and scratches are less likely to occur.

ヘツド設計、製造を容易にした。 As described above, according to the present invention, by slightly shifting the support point of the head by the support member in the direction in which the disk advances with respect to the center of the head, the surface pressure distribution at the center of the head where the gap exists can be improved. This has the effect of preventing the occurrence of abnormal vibrations and reducing the occurrence of scratches on the disk surface, which in turn simplifies head design and manufacturing.

る。 That is, according to the configuration of the present invention, the head is held by a spring member called a gimbal, and the head is able to swing freely around a support point that is an engagement portion between the support member and the head. In the head that is brought into close contact with the disk, the support point is shifted from the center part 2-1 of the head in the moving direction of the flexible disk, so that the center part of the head is pressed against the flexible disk. The present invention solves the problem of unstable contact between the disk and the head in the conventional support mechanism of this type because the support point is located in the center of the head considering only the static state, and the frictional force acts on the head and the resultant force is It was discovered that this is due to the fact that the direction shifts toward the edge of the head, and in order to solve this problem, the support point, which is the center of the swing of the head, was shifted from the center of the head in the direction of movement of the disk. . As a result, the resultant force of the vertical biasing force of the support member and the frictional force generated on the head acts on the center of the head, thereby making it possible to reliably press the center of the head against the disk.

あるというたメリツトも有するものである。 In particular, in the present application, good contact between the heads is achieved by simply shifting the position of the support point, which was originally the center of swing of the head, without using any special member to shift the position of the resultant force. It is possible to provide a head with a simple configuration that is fully adaptable to the increasing recording density, and
It has the advantage of being easy to mass-produce due to its simple configuration and being easily miniaturized.
