ている。 This type of magnetic disk device is shown in Figures 1 and 2.
As shown in the figure, it is composed of a magnetic disk 1 capable of magnetic recording, a plurality of magnetic heads 2, 2-1, 2-2 facing the magnetic disk surface, and a carriage 3 for moving the magnetic heads. The magnetic head 2 is suspended in a minute gap by the air flow generated by the magnetic disk 1 rotating at high speed, and magnetic recording and reproduction are performed. To position the magnetic head, a positioning pattern written in the disk is read out by a servo head 2-2 attached to the carriage 3, a servo loop is formed, and other data heads 2-1 are positioned.

報が読み出せなくなるという障害が起こる。 The recording density of magnetic disk devices has improved as they have been developed, and there are two ways to improve the recording density: increase the bit density of the tracks, or reduce the width of the tracks to increase the track density. . In current magnetic disk devices, the track width is 20 to 30 μm to improve track density. However, with the spread of computers, the range of environmental temperatures in which magnetic disk drives are used has expanded, so if there is a large difference in the environmental temperature during data recording or reproduction, the tracks positioned by the servo head 2-2 may This causes the data head 2-1 to shift, resulting in thermal off-track. As a result, a problem occurs in which the written information cannot be read.

あつた。 Conventionally, as shown in FIG. 3, a magnetic head 2 used in this type of magnetic disk device has a mounting portion 4 for clamping, and a mounting surface 6 of a draw bolt 5 shown in FIG. Therefore, it is installed as shown in FIG. The draw bolt 5 is pulled in the direction of the arrow A, and this tensile force fixes the head arm 2 on which the magnetic head 2 is mounted. However, when installing, the mounting surface 6 causes a galling phenomenon (a phenomenon in which the mounting surface 6 and the mounting section 4 do not slip) with the mounting section 4, so there may be a difference in thermal deformation of the mounting section due to a difference in environmental temperature. The disadvantage was that the result was a thermal off-track.

ツクを減少させることにある。 Therefore, an object of the present invention is to reduce the occurrence of galling between the draw bolt and the head arm on which the magnetic head is mounted, and to reduce the thermal off-track of the data head.

次に本考案の一実施例を示す図面を参照して本

フトラツクのバラツキが小さくできる。 The mounting surface 6 of the draw bolt 5 shown in Fig. 4 is 0.8S.
It has a mirror finish that is better than that of Surf S.
This makes it possible to prevent the galling phenomenon occurring between the mounting portion 4 of the magnetic head 2 and the mounting surface 6 of the draw bolt 5. As a result, each head arm has a stable mounting portion and undergoes thermal deformation at the same rate in response to changes in environmental temperature, thereby reducing variations in thermal off-track between magnetic heads.

がある。 As explained above, the present invention prevents galling between the head arm and the draw bolt by finishing the head mounting surface of the draw bolt with a finish of 0.8S or higher, and eliminates variations in temperature deformation between the head arms and improves thermal stability. This has the effect of reducing off-track.
