Information storage apparatus

Abstract

An information storage in which high-speed rotation of an information storage medium and high recording density of storage data are achieved. The information storage has one or more information storage media that each have a disc shape, that rotate while being secured to a common rotating shaft, and on which information is recorded; heads that approaches or in contact with the information storage media to access information; arms that extend along the surfaces of the information storage media, hold the heads on its their side, and pivot about a pivot shaft placed on the root side of the arms, and spoilers that straighten air flows between the information storage media and consist of metallic air flow control boards arranged between the information storage media; ; and a resin bracket that is formed integral with the air flow control boards and hold the air flow control boards between the information storage media.

Description

technical field [0001] The present invention relates to an information storage device having an information storage medium. Background technique [0002] Conventionally, a magnetic disk drive is known as one type of information storage device using a disk-shaped information storage medium. In this magnetic disk device, a magnetic disk is used as an information storage medium, and information is recorded or reproduced by bringing a magnetic head close to or in contact with the surface of the magnetic disk rotating at high speed. Many magnetic disk devices in recent years have a plurality of magnetic disks fixed to a common rotating shaft, and a magnetic head is supported by a carriage arm and inserted between the magnetic disks to record or reproduce information on each magnetic disk. [0003] When the disk spins at high speed, the disk creates air flow between the information storage media. Therefore, the magnetic head or the arm inserted between the information storage me...

AI Technical Summary

Problems solved by technology

[0010] However, for the metal spoiler, in order to achieve the above-mentioned large area or narrow gap, higher precision processing technology is required, so cutting processing will take more time and lead to a significant increase in cost

In addition, there is a problem that the overlap between the airflow control plates becomes deep and causes poor surface treatment to easily occur at deep positions

[0011] In addition, if the above-mentioned large area of ​​the resin spoiler is to be realized, there will be the following problems: it is necessary to control the air flow in consideration of the easy release of the mold and the warpage of the tip due to the change of time due to the low rigidity. The plate has a large slope and a thin tip, which is not good for air flow control to narrow the gap between the plate and the information storage medium

[0012] As a result, there will be the following problems: there is a limit to the large area of ​​the air flow control board and the narrowing of the gap between the air flow control board and the information storage medium, and it is difficult to improve the head positioning accuracy of the information storage device, so it is difficult Higher performance of information storage devices

[0013] This problem not only exists in magnetic disk devices, but also is a common problem in information recording devices of the type that perform information access by rotating a disk-shaped information storage medium.
