Abstract

PURPOSE:To remove efficiently dust in the inside of an enclosed device by placing a shield plate between a magnetic disc and a filter and fitting obliquely the filter. CONSTITUTION:The filter 8 is provided above the magnetic disc 2, a shield plate 9 is given between the filter 8 and the magnetic disc 2 and an enclosed cover 10 is provided in a magnetic disc, then the pressure above a clamp 4 is lowered by fir flow (pressure change) caused by the rotation of the magnetic disc 2 and the pressure is increased by the peripheral part of the magnetic disc 2, a carriage 6 and a linear motor, and the pressure difference is utilized to place obliquely the filter 8 between the pressure difference. Thus, the air in the inside of the enclosed case is given to the filter efficiently to catch dust.

However, when a filter is mounted on a magnetic disk, when the device is transported or subjected to vibrations such as shocks, dust falls from the filter surface and adheres to the magnetic disk, and when the magnetic disk is driven,
Dust enters between the magnetic disk and the magnetic head, damaging the disk and magnetic head due to magnetism, making it impossible to read or write information. In order to prevent this, the present invention provides a highly reliable magnetic disk device by inserting a shielding plate between the magnetic disk and the filter, and by mounting the filter obliquely to effectively utilize the space between the magnetic disk and the cover.

''-, it consists of a motor 3 that rotates it, and one side consists of a magnetic head 5 that writes and reads information, a carriage 6 that positions it, and a voice coil motor 7,
In a magnetic disk device that includes a filter 8 above the magnetic disk 2, a shielding plate 9 inserted between the filter 8 and the magnetic disk 2, and a cover 10 that seals them, the rotation of the magnetic disk 2 causes Due to the air flow (pressure change) that occurs, the pressure and force above the clamp 4 are low, and the outer circumference of the magnetic disk 2, the carriage 6, and the linear motor section use this pressure difference to reduce the pressure. By inserting the filter 8 obliquely, the air from the sealed interior can be efficiently passed through the filter 8, and dust can be captured.

When the magnetic disk 2 starts rotating, there is no dust between the magnetic disk 2 and the magnetic head 50, so the other side is not damaged, and a compact, high-performance, and highly reliable device can be achieved.

ように効率よく除去するかにより決まる。How to implement a filter in order to create a highly reliable, high-performance magnetic disk storage device.In other words, the magnetic disk and magnetic head that write and read information are connected to the magnetic disk with a small gap while the device is operating. If dust gets into this tiny gap above which the magnetic head floats, it will damage the magnetic disk and the magnetic head, making it impossible to read or write information. It depends on how efficiently it is removed.

However, if the filter is mounted directly on the magnetic disk, dust will fall and adhere to the magnetic disk surface from the filter surface when the device is transported or subjected to external vibrations and shocks. If the magnetic disk is rotated in this state, the magnetic head and the magnetic disk will be damaged and information will continue to be written, making writing impossible. To prevent this, a shielding plate is placed between the filter and the disk, and the shielding plate prevents dust from falling from the filter from adhering to the magnetic disk surface, making the magnetic disk device compact and highly reliable. can get.
