Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for stacking an interliner on the inside of a jacket.
The entire periphery of the jacket round hole and the head or pad movement hole provided in the jacket (the interliner is welded to this part, and the flexible disk can be rotated by being sandwiched between the interliners fixed at the edge of these holes) This is a flexible disk jacket system that is characterized by the following: This eliminates errors in the flexible disk, increases the rigidity of the jacket, and provides a jacket that can prevent damage.

To describe an example of this implementation, as shown in the drawing, a nonwoven fabric interliner 2 is layered on the inside of a plastic sheet 1 that becomes the outer skin of a flexible disk jacket, and a line 3
Then, the ears 4 are folded and welded to form an envelope shape, the flexible disk 5 is placed in the envelope, and the ears 6 are folded and welded.

The interliner 2 is welded 9 to the inner side of the entire circumference of the round hole 7 for the rotating shaft and the long hole 8 for moving the head or pad of the jacket sheet 1 (the flexible disk 5 provided here).
In addition, the interliner 2 is formed in a straight line with respect to the sheet 1 of the jacket at a portion 10 near the outer edge of the jacket and at a position 11 approximately in the center of the distance from the edge of the round hole 7 of the jacket to the outer edge of the jacket. The disc 5 is sandwiched between the interliner 2 inside the jacket and rotated.

When the disk 5 rotates, friction occurs between it and the interliner 2, and the frictional force acts on the interliner 2 around the round hole 7, causing the entire circumference of the edge of the round hole 7 to be welded 9 as in this example. If this is not done, wrinkles will occur on the edge of the interliner 2 centered around the rotational axis of the disk 5, which will cause foreign matter to be generated and adhere to the surface of the disk 5, causing errors.

A moment also occurs in the head elongated hole 8 in a direction perpendicular to the elongated hole direction.

If the interliner at the edge of the elongated hole 8 is not bonded as in this example, the edge of the interliner will be turned over and cause an error as well.

Furthermore, it is possible to prevent fibers from fraying and falling from the punched edges of the interliner in the round holes 7 and elongated holes 8, and from adhering to the disk surface and causing errors.

Furthermore, since the interliner is welded to the edge of the jacket opening, the edge is reinforced, and damage to the jacket opening, which is structurally weak, is prevented (1).

In addition, since interliner 2 is partially adhered to sheet 1 of the jacket at 9.10.11, disk 5
is in partial contact with the interliner 2 and has a cushioning property against the twisting of the interliner 2 due to the rotation of the disk 2, thereby causing less damage to the disk surface and the interliner surface and extending their service life. .

In addition, due to this cushioning property, the head pressed against the disk is surrounded by the disk, which improves the head touch and prevents the occurrence of bulge-out, and has a great cleaning effect on the disk surface.

Since the present invention is as described above, according to the inventor's actual results, the conventionally known product can be used continuously for about 50 hours, but the product of the present invention has a low output even after 675 hours of continuous operation. Astonishing experimental results were obtained in which there was no degradation, no fluctuation, and no dropout.

As described above, the present invention can provide an extremely reliable computer external storage device that does not cause errors in flexible disks, has improved durability, has little output fluctuation, and has significant industrial effects. It is.

In addition to the above-mentioned embodiments, the present invention may include various modifications of the tube in which the bonding mode and shape are changed, but all of these are included in the present invention.

Further, both a jacket alone and a jacket with a disc inserted therein are included in the present invention.
