中は。Magnetic disk drives have excellent random access and can be accessed in a short time, storage capacity can be easily increased by replacing magnetic disks, information is highly reliable, and the price per bit of information is relatively low. It is widely used as a storage device in electronic computers, mainly because it is inexpensive. In order to increase storage capacity, multiple magnetic disks are mounted on a single support rotation device.
On the other hand, a movable arm assembly on which a plurality of magnetic heads are mounted is provided so that each magnetic head is in contact with each magnetic disk, and this movable arm assembly is moved with a head position to select a desired track. do. by the way,
The magnetic disk is made of acicular magnetic particles γ2O iron dioxide (Fe2
So-called coated magnetic disks, in which 03) is mixed with I4 indica and coated on a disk-shaped aluminum (AI) alloy substrate, are often used, and during operation of a magnetic disk device.

スク、磁気ヘッド双方番こ損傷を与える可能性がある。The magnetic head is controlled so that it floats a distance of several micrometers to a fraction of a micrometer above the magnetic disk due to the action of airflow, but a magnetic disk support rotation device that supports the magnetic disk and a movable arm that supports the magnetic head are used. Since there is no airflow like this during the assembly process,
If these combination steps are performed carelessly, there is a possibility of damage to both the magnetic disk and the magnetic head.

る。Therefore, in order to reduce the risk of such damage, in the conventional process of combining a magnetic disk support rotation device and a movable arm assembly, a jig is used to temporarily fix each magnetic head. However, the effects are not necessarily satisfactory, the risk of damage is high (and, in particular, the work efficiency is extremely low).

とにある。The purpose of the present invention is to eliminate this drawback, thereby preventing damage to the magnetic disk and magnetic head in the process of assembling the magnetic disk support and rotation device and the movable arm assembly (and, moreover, greatly improving work efficiency). An object of the present invention is to provide a method for manufacturing a magnetic disk device, which has great advantages.

The purpose is to protect it by covering it with a cover of about μmn.
