Description

[Detailed Description of the Invention] (1) Technical Field of the Invention The present invention relates to a magnetic disk device, and particularly relates to a structure of a magnetic disk device suitable for a small-sized magnetic disk device.

(2) Background of the Technology Generally, magnetic disk devices are widely used as external storage media for information processing devices and the like. Subsystems equipped with multiple magnetic disk devices are also being developed.

In particular, in a large magnetic disk device used in a large computer system, the magnetic disk device and the magnetic disk control device are housed in separate casings, and are installed separately from the casing of the central processing unit.

On the other hand, magnetic disk devices have come to be used in small computers, personal computers, and the like.

Therefore, it is particularly desired that the small magnetic disk device used as a built-in device be easy to handle.

(3) Prior art and its problems Fixed-type magnetic disk devices have become mainstream in conventional magnetic disk devices, especially small magnetic disk devices. The magnetic disk, head, and head access mechanism were housed in a housing, and the control section that controlled them was separated from the housing.

Therefore, when built into a computer,
The casing and the circuit for controlling it must be housed separately, and even when supplying magnetic disk drives to computer manufacturers, the mechanical part and the control part are supplied separately, making it difficult to manufacture. There were problems with cost and poor maintainability.

(4) Purpose of the invention The purpose of the invention is to solve the above-mentioned problems by creating a magnetic disk device that is particularly effective in small-sized magnetic disk devices and that facilitates installation and removal from a computer, transportation and maintenance of the magnetic disk device. It is about providing.

(5) Structure of the invention In order to achieve the above object, the invention provides a magnetic disk, a spindle equipped with the magnetic disk,
A disk unit housing a head and a head drive unit; a drive circuit for driving the spindle and the head drive unit; and control for transmitting and receiving signals with a host controller and controlling the entire device. A package on which at least a circuit is mounted, and the disk unit and the package are integrally provided with a card edge type connector at one end for receiving and transmitting signals to and from a host control device and receiving power supply. The device is characterized in that it is configured to be connected to a device mounting rocker or the like via the connector.

That is, the magnetic disk device of the present invention has a unit that houses mechanical parts such as a disk head and a head drive section, and a host control device such as a computer system that is equipped with a built-in circuit for driving these mechanical parts. A package (printed board) equipped with an interface circuit (signal transmitting/receiving part) is integrated, and this unit becomes a magnetic disk device.A card engine type connector is placed at one end of the package to connect the signal transmitting/receiving part and the power supply. By centralizing the part that receives the supply, the connector can be connected to the locker on which the magnetic disk device such as the computer main body is mounted, and it is possible to attach and detach the magnetic disk device to the computer main body, transport the magnetic disk device, and maintain it. made it easier.

(6) Embodiment of the invention The present invention focuses on the miniaturization and weight reduction of fixed magnetic disk drive mechanisms in recent years, and the high integration and cost reduction of electronic circuits such as magnetic disk drive circuits and control circuits. By combining the two, a magnetic disk device is constructed.

The present invention will be explained below with reference to examples.

FIG. 1 shows an example of a system configuration of a magnetic disk device according to the present invention.

In the figure, magnetic disk devices 3-1 to 3-N
Information signals and control signals are connected (solid lines) to a disk control device 1 (in a small system, it may be a computer main body) to send and receive information and control the magnetic disk device. Further, power is supplied from the power supply unit 2 to each of the magnetic disk drives 3-1 to 3-N, and is used to drive the disks and heads and to drive the electronic circuits within the magnetic disk drives.

FIG. 2 shows the configuration of the magnetic disk device of the present invention.

In the figure, the disk units 3-1 to 3-N shown in FIG. 1 are indicated as disk unit 3;
Disk control circuit and drive circuit 7 on package 8
is mounted, and furthermore, a head drive section 13 for driving the head 6, a disk 4, a spindle section 5, etc. are mounted to constitute one unit.

That is, the magnetic disk 4, spindle 5, and head drive section 6 are housed in a housing, and a disk control circuit and a drive circuit 7 are mounted on a package (printed board) 8 that is integrated with the housing. There is.

A connector 9 (card edge type connector) is provided at one end of the package 8 for receiving and transmitting information signals and control signals from a host control device and for receiving power supply.

In this way, the magnetic disk device becomes operable by connecting it to a computer, which is a higher-level control device, via this connector 9.

For example, in such a magnetic disk device, the third
As shown in the figure, a disk system locker 10 for configuring a disk subsystem is provided, and this locker 10 is attached to a disk unit 3.
Each space is partitioned to accommodate multiple
Insert a disk device into 1 and configure the system.

By installing the disk unit shown in Fig. 2 into the system locker shown in Fig. 3, power is supplied through the connector, and the disk control device, information signals, and control signals are connected, and the system locker is connected. Operation becomes possible.

Also, when the disk unit is not being used on the system, it can be removed from the locker.
The disk can be separated from the system and can be stored and transported.

(7) Effects of the invention As explained above, according to the invention, the handling of the magnetic disk device is simplified, thereby reducing manufacturing costs, increasing the reliability of the device, and facilitating maintenance. This also has the effect of increasing the portability of the device.

Furthermore, since all of the signal system and power supply system for the magnetic disk device can be connected through a connector provided at one end, the device can be attached and detached extremely easily.
