本考案は、磁気デイスク装置に関し、特に回転
型位置決め機構を主基板に取り付けた磁気デイス
ク装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a magnetic disk device, and particularly to a magnetic disk device in which a rotary positioning mechanism is attached to a main board.
従来、この種の磁気デイスク装置は、回転型位

Conventionally, in this type of magnetic disk device, a rotary positioning mechanism has been fixed to only one side of the main board.
However, with the recent increase in capacity and speed,
It has become necessary to increase the rigidity of the main board and the rotary positioning mechanism, and recently a structure has been developed in which the rotary positioning mechanism is attached to the main board from both sides.

置決め機構の上部補助基板と前記主基板との間に
シムを挿入することにより、前記回転型位置決め
機構を前記主基板に固定していた。 By the way, when the rotary type positioning mechanism is installed in the main substrates on both opposing sides, a certain gap is created between the rotary type positioning mechanism and one of the main substrates. In order to minimize the gap, it is necessary to increase the dimensional accuracy of the main board on both sides and the assembly accuracy of the rotary positioning mechanism, and to install a shim between the upper auxiliary board of the rotary positioning mechanism and the main board. By inserting the rotary positioning mechanism, the rotary positioning mechanism was fixed to the main board.

In the above-described conventional magnetic disk device, if the dimensional accuracy of the main board and the assembly accuracy of the rotary positioning mechanism are poor due to manufacturing difficulties associated with the insertion of shims, the main board and the rotary positioning mechanism may Since the magnetic disk and the arm are fixed in a deformed state, the relative dimensions of the magnetic disk and the arm cannot be determined, and vibrations are adversely affected.

The present invention provides a magnetic disk device having a plurality of magnetic disks included in an upper main board and a lower main board, and a rotary positioning mechanism for operating a magnetic head section located opposite to the magnetic disks. A sleeve is attached to the main board in a height-adjustable manner, and one end of the sleeve is pressed against the upper auxiliary board of the rotary positioning mechanism by changing the height position of the sleeve. This magnetic disk device is characterized in that the upper main board and the upper auxiliary board are screwed together by interpolating the gap between the upper main board and the upper auxiliary board.

As explained above, the present invention presses the cylindrical sleeve provided on the upper main board against the upper auxiliary board and interpolates the gap, thereby preventing the main board and positioning mechanism from deforming. It is possible to reduce the vibration level, and there is no need to increase the dimensional accuracy of the main board or the assembly accuracy of the rotary positioning mechanism.
This has the effect of making manufacturing easier.
