Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a door mechanism for a contact start strike, F-type magnetic disk device.

[Technical background of the invention and its problems] Generally speaking, in a magnetic disk drive device using a contact start strike or FM magnetic head, clean air is always filled in order to prevent the magnetic disk from being loaded. Care must be taken to prevent ilK dust from adhering.

Therefore, conventionally, a sealed structure is adopted in which the atmosphere of a potentially dangerous magnetic disk, magnetic head, etc. housed in the apparatus main body is pressurized so that it communicates with the outside air only by an air filter provided at a predetermined portion of the apparatus main body. For this reason, in the past, the above-mentioned contact start strike, F type magnetic head was mainly used in single fixed running disk MOS disk drives.
・In fixed disk type magnetic disk drives using this type of contact start strip FG, the assembly is carried out in a clean room, and clean air is sealed in the atmosphere of the magnetic disk, magnetic head, etc. The intrusion of dust from the outside can be prevented by using a magnetic r disk of such a contact starter fsI for a fixed disk device.

In recent years, the development of a so-called cartridge type magnetic disk device has been progressing, which uses a contact start strike, F-type magnetic head and has replaceable disks. In this type of cartridge type magnetic disk device, as in the case of the fixed disk type described above, it is necessary to take measures to prevent dust from entering from the outside, but when replacing the cartridge, the magnetic disk inside the Fi
Dirty outside air enters the atmosphere of the magnetic head, etc., leading to the intrusion of dust. Therefore, replacing the cartridge and cartridge can be done quickly and easily, and moreover, once the cartridge is attached, it prevents the intrusion of dust from the outside. There is a mechanism that can reliably prevent this.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and when a cartridge-type magnetic disk device is constructed using a contact start-stop type magnetic head, a disk cartridge,
This cartridge-type magnetic disk device has a structure in which the cartridge can be quickly and easily attached and detached, and the air sealing effect for the cartridge attachment/detachment opening is significantly improved, greatly increasing the effect of preventing dust from entering. Aim to provide door mechanism t-.

[Summary of the invention]

The present invention relates to a door structure for a disk cartridge and a disk drive opening when a cartridge and disk type reef air disk device is constructed using a contact start-stop type magnetic head.
The receiver that guides and holds the disk cartridge and disk inside the device body is connected to the door structure, and an interlocking mechanism is provided that moves the receiver up and down as the door is opened and closed, making it easy to attach and remove the disk cartridge. and when the door is closed, the disc cartridge including the interlocking mechanism and the opening part for the screw attachment are air-sealed with an endless gasket member, which allows the scissors to be attached and detached from the disk cartridge. This makes it possible to improve the effectiveness of preventing dust intrusion while making the product more compact, thereby further improving functionality and reliability.

[Embodiments of the invention]

One embodiment of the present invention will be explained below with reference to the figures. Recommendation 1
The figure relates to the first implementation of the present invention; it is a side cross-sectional view showing a schematic configuration of a cartridge type magnetic disk device using a magnetic head manufactured by Nukto Start Stop. In the figure, l is a disk cartridge; A magnetic disk plate (hereinafter simply referred to as a disk) J fixed by an internal FcFi hub 3 and an armature 4 made of a magnetic metal material screwed to the hub 3 are provided. This disk cartridge and disk cartridge 1 can be replaced. 8 is contact start strike y 7' III 1 is Ki head, middle'r

6F17'' is a receiver for holding the disc cartridge 1, and moves up and down in the direction of the arrow 20 from the center of the fulcrum part 7t to hold the disc cartridge 1 on the flange 1.
You can remove the IO attached to 2. When the disk cartridge 1t is inserted or removed, the disk 8 is held away from the surface of the disk 2 due to the thermal magnetism. The mechanism for this is omitted in the figure. 11, 4 is pace, 18 is switches/mother panel, 1

The door part 16 and the receiver 6 are connected to each other by an interlocking mechanism such as a link or a cam, which will be described later.
When the door 1# is opened, the receiver 6
rotates upward as shown by the arrow 20 around the fulcrum 7, and this
Therefore, the disk cartridge 1 is the spindle motor 11.
It is separated and can be taken outside. When the disc cartridge is inserted into the JFi receiver 6 and the door 16 is closed, the disc cartridge is set at the regular position. When door 16 is closed, disc I

The receiver 6 is rotated around the fulcrum part 7 by the link cam mechanism consisting of the 3% cam 24, the struts zs and xg, and the cartridge and the outlet are lifted upward, and the disc cartridge and the disc are moved to the receiver 6. It will be in a state where it can be taken out more easily. In addition, when the disk cartridge 1 is inserted into the receiver 6 and the door 1# is closed as shown in FIG. The link cam mechanism that moves up and down 6 is securely placed in the atmosphere of the disk 2 and magnetic head 8. Gasga again, TozzF
It has an endless shape, and the part surrounded by this gasket S2 is K to create an extremely airtight seal.
The opening shown in Figure 0 shows that the opening of the door 16 is provided with a closing mechanism. In good condition, the p-lock mechanism works and pressure is applied to gasket 3j. Here, the distance between the fulcrum part S1 of the door 16 and the gasket J2 is taken into consideration so that the deflection of the gasket 32 to keep the tube away from the pipe does not become excessive.

By housing the movement mechanisms of the door 16 and the receiver 6 together in the interior as described above, the door can be sealed with the outside air at one location using an endless gasket, resulting in very good air sealing performance.
