JPS6151682A - Detachable construction of magnetic disk - Google Patents

Abstract

PURPOSE:To set a fixed interval of a disk and a head in the smallest and most suitable manner and to increase a unit surface recording capacity of a magnetic recording surface by detaching together with a head with a detachable magnetic disk and a magnetic head as a single construction. CONSTITUTION:When information is written or read between a magnetic disk device 1 and an external device 2, the device 1 is fitted to a storing box 3, a connector inserting part 4 and a socket part 5 are linked and a power source line, an information and a control line between the device 1 and the device 2 are linked. After that, a writing or reading command is executed for magnetic recording media of the device 1 by the device 2. When information is preserved, the device 1 is removed from the storing box 3 and the device 1 is preserved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic disk device for an information processing device. In particular, it relates to improvements in means for attaching and detaching magnetic disks.

[Conventional technology]

Conventional magnetic disk drives have a structure in which a magnetic recording medium such as a flexible disk can be directly attached or detached due to a disk puncture. had taken out the magnetic recording medium and stored it. As the magnetic recording medium is attached and detached, a mismatch occurs in the relative position of the magnetic head and the magnetic recording surface. In order to overcome the inconvenience caused by this phenomenon, a method has been adopted in which the recorded pitches are increased by the amount of undefeated pitches at this position.

[Problem that the invention seeks to solve]

Such conventional magnetic disk drives have the disadvantage that the storage capacity per unit magnetic recording surface decreases because the recording pitch is excessively widened to cope with the problem.

SUMMARY OF THE INVENTION The present invention aims to eliminate the above-mentioned drawbacks, and aims to provide a magnetic disk mounting means that can prevent the occurrence of inconsistency in the position of the magnetic head and the magnetic recording medium due to attachment and detachment.

[Means for solving problems]

The present invention provides a structure for attaching and detaching a magnetic disk to a large external device, and as a means to solve the above-mentioned drawbacks, the magnetic disk to be attached and detached and the magnetic head of the magnetic disk are integrated into an integrated structure. A removable electrical connector for connecting an electric circuit is provided between the device and the external device, and the integrated structure is held in a fixed position on the external device by bringing the electrical connector into a connected state. .

[Effect]

The magnetic disk and the magnetic head, which are to be attached and detached, have an integral structure, and the magnetic disk is attached and detached from the device together with the magnetic head. As a result, the distance between the magnetic disk and the magnetic head becomes fixed, and the distance can be set to the minimum and optimum value.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A device according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the external shape of a magnetic disk device constituting the apparatus of this embodiment. FIG. 2 is a perspective view showing the outer shape of an external device constituting the apparatus of this embodiment. FIG. 3 is a partially cutaway side view showing how the magnetic disk device shown in FIG. 1 and the external device shown in FIG. 2 are coupled.

This embodiment device includes a magnetic disk device 1 and an external bag=2.
The magnetic disk device 1 is provided with a connector insertion portion 4, and the external device 2 is provided with a storage box 3 to which a connector receptacle portion 5 is fixed. The magnetic disk device 1 has a built-in magnetic recording medium, a magnetic head spindle motor, an actuator, a read circuit, and a write circuit, and an external device 2 is connected to the magnetic disk device 1 and writes information to or from the magnetic recording medium. The storage box 3 has sufficient space to store the magnetic disk device 1, and the insertion section 4 is provided with a means for reading information from the magnetic disk device 1 and a means for processing the information. It is a pin-structured connector including a power supply line, an information line, and a control line to be connected, and the socket part 5 is a pair of socket-structured connector with the insertion part 4.

Next, the operation of the apparatus according to the present invention will be explained based on FIGS. 1 and 2.

When writing or reading information between the magnetic disk device 1 and the external device 2, the magnetic disk device 1 is installed in the storage box 3, and the connector insertion portion 4 and the connector socket portion 5 are connected. and magnetic disk device 1 and external device 2.
After connecting the power line, information line, and control line between the magnetic disk drive 1 and the magnetic disk drive 1, the external device 2 issues a write or continuous output command to the magnetic recording medium of the magnetic disk device 1. Further, when storing information, the magnetic disk device 1 is taken out from the storage box 3 and the magnetic disk device is stored.

〔Effect of the invention〕

As described above, the present invention has the effect of increasing the storage capacity per unit magnetic recording surface by attaching and detaching the magnetic disk device itself in which the relative position between the magnetic head and the magnetic recording medium is optimized. be.

In particular, magnetic disk drives have recently become smaller and cheaper, and the cost performance improvement effect of the present invention is increasing.
