く低下するという問題を有していた。However, in the conventional example described above, the helad mount members are mutually
Since the head mount assembly is fixed with only one screw, for example, if vibration or impact is applied to the magnetic disk drive, the head mount members may shift from each other, causing the S air that is supported and fixed to the head mount to The head is also misaligned,
This causes off-track between magnetic heads. The above-mentioned off-track between the a-heads can occur not only in open-loose magnetic disk devices that do not perform track initial pressure based on position information on the recording medium, but also in magnetic disk devices that perform position correction. There are many devices that cannot be corrected if there is a difference. For this reason, the above-described fixing method has a problem in that when vibrations or shocks 7 are applied to the device, the magnetic heads are misaligned with each other, and the reliability of the magnetic disk device is significantly reduced.

第１図に本発明による実施例を示し、詳細に説明する。The magnetic disk drive of the present invention prevents the head mounts from shifting due to vibrations and shocks by fixing the head mount members to each other at two places using the head mount assembly screw and the head mount pin, and provides high-speed access. [Embodiment] FIG. 1 shows an embodiment of the present invention, and will be described in detail.

2, 13, 14) are mutually fixed by a head mount assembly screw (15) and a head mount pin (16). (17) is a screw for attaching the head mount members fixed to each other in the above-described manner onto the carriage (18).

化しても固定力の変化しない特徴も合わせて有する。According to the above embodiment, even if vibrations and shocks are applied to the magnetic disk device, the head mount members do not shift relative to each other, so that a highly reliable magnetic disk device can be provided. Furthermore, since one side is a pin, it is lighter in weight than when both are fixed with screws, which reduces the load on the drive motor (19) and enables high-speed access.
In addition, if the pin is knurled and press-fitted, the tolerance between the pin and the large hole can be increased, and the workability can be improved. Furthermore, if the material of the pin has approximately the same coefficient of thermal expansion as the head mount member, it also has the characteristic that the fixing force does not change even if the operating temperature environment of the magnetic disk device changes.
