Description

DETAILED DESCRIPTION OF THE INVENTION (Field of the Invention) The present invention provides a method for storing a hard disk on which digital signals are recorded rotatably in a case, and loading the hard disk in a turntable while being housed in the case. The invention relates to a disc cartridge that is used.

(Background of the Invention and Prior Art) Hard disks for recording data as digital signals have been known. This hard disk is
For example, digital signals are optically recorded on a recording surface provided on a glass or acrylic substrate.

It is recorded according to an appropriate method such as magnetically, magneto-optically, or mechanically.

Conventionally, this disc was attached to and removed from the turntable as a single unit,
Jackets were used to transport and store the discs. Also, to avoid the hassle of putting discs in and out of jackets, there were cartridges that could be loaded into turntables with discs still in them, but these were mainly intended to make handling easier; Protection was insufficient.

(Problems to be Solved by the Invention) Since the disk uses a substrate such as glass or acrylic plate, there is a problem in that it is easily damaged when subjected to impact such as dropping during transportation. Furthermore, when a jacket intended for impact resistance is used, dust and fingerprints tend to adhere to the disc when the disc is inserted or removed, and furthermore, it is inconvenient to handle the disc by inserting or removing it from the jacket.

The present invention has been made in view of these points, and it is an object of the present invention to provide a disk cartridge in which the hard disk is easy to handle, dust and fingerprints do not adhere to it, and the disk is less likely to be damaged.

(Means for Solving the Problems) The present invention is a method for solving the above-described problems, and includes a chucking window that rotatably accommodates a hard disk that records data as a digital signal, and a chucking window that faces the center of the disk. A disk characterized in that it comprises a casing in which a data recording/reproducing window is formed facing a recording section of the disk, and a support section provided within the casing to support an outer peripheral edge and upper and lower surfaces 3 of the disk. The cartridge achieves nine objects of the present invention.

Here, the support part is not only formed integrally with the casing, but can also be held separately from the casing through an elastic material within the casing. In the latter case, the damage to the disk is effectively absorbed by the deformation of the elastic material, so that the protection of the disk becomes even more reliable. Also, the gap between the disk and the support part is 1.0 to 4.0 mm or 1.0 mm between the opposite side and the support part when the disk is moved to one side.
It is preferable to set the distance to 5.0 mm.

(Actual IM Mode) FIG. 1 is a partially cutaway plan view of one actual reduced M% according to the present invention, and FIG. 2 is a sectional view taken along the line If-n.

In one of these, the symbol IO is a hard disk. This disk 10 has a recording surface on one side of, for example, a donut-shaped glass or acrylic plate, and is made of two glasses with the recording surfaces facing each other.

A spacer 3 or an acrylic plate are placed facing each other and fixed to each other with a spacer 3 interposed therebetween. The spacer on the inner peripheral side is made of a metal plate such as aluminum, and has a chucking hole 12 formed in the center. The disk 10 is attached to and detached from a turntable (not shown) that rotationally drives the disk 10 through this chucking hole 12.

It is a disk cartridge housing with a substantially square plan view that rotatably accommodates 20 size 10 disks.

An upper half body 22 and a lower half body 24 are stacked on top of each other so as to form a storage area for the disk 10 inside them. A chucking window 26 having a diameter larger than the chucking hole 12 is formed in the upper and lower halves 22 and 24 of the housing 20 at the center of the disk IO. Also, upper and lower body 22.
A data recording/reproducing window 28 is formed in the disc 24 so as to face the recording section of the disc 10 . This window 28 is provided with a shutter (not shown), which opens when the disk cartridge P is loaded into the recording/playback device and closes when the disk cartridge P is not loaded into the device. ing.

The four corners of the casing 20 are provided with an outer peripheral edge that faces the outer peripheral edge of the disk 10. A support portion 30 is provided for support. In this embodiment, each support section 30 is connected to the upper and lower halves 2 of the housing lO.
2. A boss 32 protruding from a surface other than the peripheral edge of the disc 10, that is, a surface parallel to the disk 10, an annular rubber elastic member 34 fitted into the boss 32, and a hard member supported by the elastic member 34. The four-fingered shock receiver is composed of a member 36.

In the gfJS receiver, the portion of the member 36 facing the circumferential edge of the disk 10 is formed in an arc shape.

On the inner surfaces of the upper and lower halves 22 and 24 of the housing 20.

A support portion 38 is disposed near the inner circumference of the disk IO, for example, on the upper and lower surfaces facing the non-recording portion, so as to protrude from the other inner surfaces. In this actual ffarrLQ, the support portion 38 is formed of an annular rubber elastic material.

A disk cartridge configured like this.

It is assembled with the disc stored inside.

The disk 10 is transported or stored while being kept in the housing 20. The entire cartridge can also be attached to and removed from the turntable. At this time, the turntable is engaged with the chucking hole 12 of the disc 10 and the disc 10 is connected to the fan housing 2.
Move it slightly within 0.

The disk 10 is held in a position where it does not come into sliding contact with the housing 20 or the support section 30. In this state, the disk 10 rotates,
The shutter of the data recording/reproducing window 28 is opened, and the data recording/reproducing head (not shown) 1' faces the disk IO.

If a shock is applied to the cartridge during transportation, etc.

The disk 10 is protected by the impact bearing hitting the member 36 and by the deformation of the elastic material 34.

Further, the support portion 38 made of an elastic material on the inner surface of the housing 20 also absorbs the impact. As a result, the disk IO will not be damaged. Further, since the disk 10 is transported and stored while being kept in the housing 20, dust, fingerprints, etc. do not adhere to the disk 10.

If the gap between the disk 10 and the support portions 30.38 is too small, the disk 10 will easily hit the support portions 30.38 when the disk 10 rotates, and if it is too large, it may cause a shock to be applied to the disk 10 when a cartridge is dropped. The amount of bounce of the disk 10 inside the housing increases, making it easy to damage the disk 10 and cause distortion. It is more likely to occur. Furthermore, if this gap is too large, it will be difficult to attach and remove the disk from the turntable when the cartridge is loaded onto the turntable, and the disk will move significantly within the cartridge, making the operator feel uneasy. As a result of nine different experiments, the inventor found that when the disk 10 is moved to one side within the housing, the gap is 1.0 mm between the other side of the disk and the radial support portion 30.
0 mm to 5.0 mm, and 1.0 mm to 4.0 m between the other side of the disk and the support portion 38 in the thickness direction.
I learned that it is best to set it within the m range.

FIG. 3 is a partially cutaway plan view of another embodiment, and FIG. 4 is a sectional view taken along line IV-rV11. In this embodiment, the support part 30F in the embodiments in FIGS. 22
An annular support member 32A and a shock receiver member 36A, which are held so as to be slightly movable between A and 2ψA, and both members 32A.

36A and a rubber elastic member 34A loaded between the two. Are the same parts in Figures 3 and 4 the same as those in Figures 1 and 2? Since I have attached it, I will not repeat the explanation.

In each of the above embodiments, rubber is used for the elastic members 34, 34A, but it goes without saying that a metal plate spring or the like may be used instead of rubber.

Further, although the supporting parts 30.3OA and 38 are separate from the housing 20.20A, they may be formed integrally with the housing in the present invention. In this case, the support portion facing the outer periphery of the disk is located at a location other than the periphery of the casing.

In other words, it is desirable to provide it on a plane parallel to the upper and lower surfaces of the disk. In this case, the casing? In the event of a fall, the impact will not be transmitted directly to the disc from the edge of the casing.

Disk protection becomes even more reliable.

(Effects of the Invention) As described above, the present invention rotatably accommodates a hard disk in a casing in which a chucking window and a data recording/reproducing window are formed, and the outer periphery and upper and lower surfaces of this disk are covered with a casing. Since it is configured to be supported by a support section provided inside the body, the disk can be transported and stored while it is in the casing, making it easy to handle the disk and preventing damage to the disk. It also prevents dust, fingerprints, etc. from adhering to the disc.
