Description

[Detailed explanation of the invention] (1) Technical field of the invention The present invention relates to a floppy disc, and in particular, a floppy disk that has a lid that can be opened and closed in the opening of the jacket to prevent damage to the built-in magnetic disc.
It is related to disks.

(2) Background of the technology It is well known that in recent years, floppy disks have been widely used in all fields of computer systems due to their easy handling, small size, and relatively large storage capacity. .
However, although the floppy disk has the advantages mentioned above, the capacity of the floppy disk is insufficient for the user. In order to deal with this shortage, floppy disks have been prepared for each purpose and type of product used, and the floppy disks for the required purposes have been used interchangeably, taking advantage of their good handling and operability.

(3) Problems with the prior art Figure 1 is a plan view for explaining a conventional floppy disk, in which 1 is a flexible magnetic disk, 2 is made of paper, etc., and there are openings for reading and writing information. This is a jacket provided with a section 21.

A floppy disk has a structure in which a magnetic disc 1 is housed in a jacket 2 for storage, but since the jacket 2 has an opening through which a magnetic head for reading and writing information faces, it is difficult to store the disc in a magnetic disk device. During installation and replacement work, the surface of the magnetic disk exposed at the opening 21 of the jacket may be damaged by dust, etc., or may become contaminated with oil from hands, causing problems such as head crushing.

(4) Purpose of the invention In view of the above-mentioned conventional problems, the object of the present invention is to provide a new floppy disk that prevents problems caused by the jacket opening.

(5) Structure of the invention In order to achieve the above-mentioned object, the present invention provides a floppy disk consisting of a flexible magnetic disk and a jacket for storing the magnetic disk, and a method for reading and writing information on the jacket. This is achieved by attaching a protective cover to the opening that can be opened and closed.

(6) Example of implementation of the invention The following is an example of a floppy disk according to the invention using drawings.
A preferred embodiment of the disk will now be described in detail.

FIG. 2 is a diagram for explaining one embodiment of the present invention, in which a is a plan view of the main part of a floppy disk, b, c, and d are side cross-sections of the main part in a state where it is attached to a floppy disk device. The figures are shown respectively, and parts equivalent to those in the previous figure are given the same reference numerals. In these figures, 3 is the jacket 2
One end is attached to the center side of the magnetic disc 1 via a spacer 4 so as to be openable and closable, and the other end is fitted with a magnetic head 5. It is a transparent lid made of vinyl chloride with a sloped part 31 formed for ease of use. According to the hidden floating disc, the lid 3 is closed when not in use.
This protects the magnetic disc surface exposed in the opening 21 of the jacket 2, and also prevents dust and the like from entering there.

Therefore, when using the floppy disk, when the operator manually inserts it into the floppy disk device in the direction of arrow A (see FIG. 2b), the lid 3 attached to the opening 21 of the jacket 2 opens.
The inclined portion 31 is pushed up and opened when it comes into contact with the stopped magnetic head 5 on the device side. In this state, if the floppy disk is pushed further into the permitted position against the elasticity of the lid 3, the magnetic head 5 will stop at a position corresponding to the outer end of the opening 21 of the jacket 2. A state in which this installation is completed is shown in FIG. 2c. When the operator finishes the predetermined information writing/reading operation and pulls out the floppy disk from the device, when the operator pulls out the floppy disk by hand in the direction of arrow B, the magnetic head 5 is removed from the lid 3, and the lid 3 is Returning to the current state, the magnetic disk 1 exposed through the opening 21 of the jacket is protected. This state is shown in FIG. 2d.

(7) Effects of the invention As is clear from the above explanation, the floppy disk according to the invention does not have the information reading/writing openings exposed when not in use, unlike conventional disks, making it easier to handle. It can be expected to prevent damage to the magnetic disk, etc., and has the advantage of extending its life.

[Brief explanation of the drawing]

FIG. 1 is a plan view for explaining a conventional floppy disk, and FIG. 2 is a diagram for explaining an embodiment of the floppy disk according to the present invention.
A shows a plan view of the main part, and b, c and d show a side sectional view of the main part in the operating state. In the figure, 1 is a magnetic disk, 2 is a jacket,
3 is a lid, 4 is a spacer, 5 is a magnetic head, 21 is an opening for reading and writing information, and 31 is a sloped portion.

Claims (1)
