Claims

[Claims for Utility Model Registration] A floppy disk that is inserted into and set in a floppy disk device equipped with a shutter opening mechanism and a magnetic head, and on which data is written or read by the magnetic head, A disk recording medium 10 is formed into a rectangular flat box shape using an insulating resin material, and the disk recording medium 10 has a center window 21 provided on one side and a central window 21 provided on both sides, extending from the center of one side toward the inner side. A shell 2 is exposed and accommodated in a head window 22 having a predetermined width and length, and the thickness of the shell 2 is made of an elastic material and is the length of the inside of the base, and the shell 2 is exposed from one side of the shell 2 to the head window. The shell 2 is formed in a U-shape with the length covering the shell 22 being the length of both sides, and has a window portion 31 of approximately the same size as the size of the head window 22 and a shielding portion that covers the head window 22. a shutter 3 that is slidably sandwiched between both sides of the U-shape from the thickness direction along the one side and is biased by an elastic member 4 to shield the head window 22 with a shielding portion; a guide means 24 for guiding the shutter 3 sliding along one side; and a guide means 24 provided on the inner side of the head window 22 of the shell 2 and at least on the side where the center window 21 is located, and provided in the U-shape of the shutter 3. and a blocking means 25 for preventing the tips on both sides of the shell 2 from leaving the surface of the shell 2, and when the floppy disk is inserted into the floppy disk device, the shutter opening mechanism opens the shutter 3.
The guide means 24 resists the elasticity of the elastic member 4.
The window portion 31 moves to the position of the head window 22 while being guided by the head window 2.
2. A floppy disk characterized in that floppy disk 2 is configured to face the magnetic head.
