Abstract: A recording medium cartridge comprises an information recording medium, an inner rotor, and a pair of shutter members that are piled and accommodated in a cartridge casing. When the inner rotor is rotated, the opening part of the cartridge casing is opened and closed by the shutter members. On the overlapping surface of the shutter and the inner rotor, a plurality of ribs for reducing the contact area of the shutter and the inner rotor are provided. Further, in side parts of the shutter members, first overlapped parts and second overlapped parts are respectively provided through first step parts and second step parts in the moving directions of the shutter members. When the side parts are overlapped on each other, the first overlapped part of one shutter member and the first overlapped part of the other shutter member are continuously connected together through the first step parts on the upper surface side of the shutter members. In the lower surface side of the shutter members, the second overlapped part of one shutter member and the second overlapped part of the other shutter member are continuously connected together through the second step parts to close the opening part for recording and reproducing information provided in the cartridge casing. The first step parts and the second step parts are arranged in non-overlapped positions. Thus, the contact area of the inner rotor and the shutter on the overlapping surface is reduced to smoothly move the pair of the shutter members. Further, when the pair of the shutter members are closed, the step part exposed on the front surface of the shutter members and the step part exposed on the back surface of the shutter members are reinforced.

Abstract: A magnetic disk cartridge which is used with a high density recording magnetic disk and which provides good recording and reproducing properties. The magnetic disk cartridge has a flexible magnetic disk having a disk-like center core. The upper surface of the disk-like center core is centrally affixed to the magnetic disk. The magnetic disk is rotatably retained in a flat housing. The magnetic disk has a surface recording density of at least about 158.7 Mbit/cm2. The disk wobbling value of the magnetic disk measured at a radial position located 5 mm outward from the outer diameter of the center core of the magnetic disk while rotating the magnetic disk by means of a drive device via the center core is not more than 20 nullm.

Abstract: To make it possible to keep a disk-like recording medium accommodated in a case under a stable state without shaking and to easily take it out, a receiving table on which a center portion of a disk is put is so formed at a base center of a main body as to protrude from a base surface. An outer peripheral edge for supporting thereon a disk outer periphery protrudes from the receiving table as a center. A removable member for supporting the outer periphery of the disk and engaging with the outer periphery is disposed by cutting off a part of the outer peripheral edge. The removable member includes a lift portion for supporting thereon the disk outer periphery, formed inside a rocking lever and a button formed outside the lever. Hooks for engaging with the disk outer periphery are provided to the lever.

Abstract: A disk cartridge includes a casing, a recording disk, and a liner which is fixed to an inner surface of the casing or a shutter member interposed between the disk and the casing at a site opposed to the disk in order to clean the surface of the disk. The liner is supported away from the inner surface of the casing or the shutter member so that the liner can be deflected when the disk is brought into abutment against the liner due to impact applied to the disk cartridge.

Abstract: A cartridge for an information recording medium includes a cartridge case, an opening cover, detachably mounted to a rear side opening of the cartridge case, for enabling the information recording medium to be withdrawn or inserted with respect to the cartridge case, and a holding unit for preventing movement of the information recording medium by supporting the information recording medium when the information recording medium is received and/or withdrawn into/from the cartridge case. The holding unit includes a pair of elastic pressure parts, elastically formed on the opening cover, for elastically supporting the information recording medium to prevent movement of the information recording medium when the opening cover is not attached to the cartridge case, and a release unit for releasing the pair of elastic pressure parts when the opening cover is attached to the cartridge case so that the information recording medium is rotatable in the cartridge case.
