Abstract

PURPOSE:To secure a constant pitch even with a thick magnetic disk and at the same time to prevent the deterioration of the mechanical rigidity, by forming cut grooves with a shift at the upper and lower sides of each tip part of a head arm, fixing the rear edge part of a head supporting tool to each groove and also fixing a head to the tip part of each supporting tool. CONSTITUTION:Cut grooves 5a and 5b are set with a shift at the upper and lower sides of a head arm 5, and the rear edge part of each head supporting tool 4 is attached to each cut groove. A head 3 is fixed to the tip part of each tool 4. In such a constitution, the disk pitch is not increased even with use of a thick magnetic disk. Furthermore no deterioration is given to the mechanical rigidity of the arm 5. This gives no limitation to the length of a screw for attachment of the tool 4.

さの薄りヘッドアームを使用しなければならなかった。Therefore, in conventional magnetic disk drives, when a thick magnetic disk is used with the distance between the surfaces of adjacent magnetic disks unchanged, the pitch of the magnetic disks becomes large. In addition, in conventional magnetic disk drives, when the pitch of the magnetic disk remains unchanged and a thick magnetic disk is used, the distance between the surfaces of adjacent magnetic disks tends to be small, so it is necessary to reduce the distance between the heads. I had to use a thinner head arm.

力ければガらない等の欠点が生じた。If a thin head arm is used, the mechanical rigidity of the head arm will decrease, and if a screw is used to attach the head support to the head arm, the length of the screw will be limited and it will not come loose with force. A shortcoming occurred.

The purpose of this invention is to provide a magnetic disk device that is possible.
