摘要： A magnetic disc cartridge is composed of a pair of upper and lower case members so as to form a hard case to accommodate a magnetic disc therein. An aperture for access of a read-write head to the magnetic disc extends in a radial direction, which aperture is selectively covered by a shutter. The case has a groove on the peripheral edge thereof to receive a shutter actuation pin. The groove extends across the adjoining surfaces of the two case members. A groove portion defined by the lower case member is more enlarged than the remaining groove portion defined by the upper case member so that the shutter actuation pin does not catch in the step between the two groove portions.
摘要翻译：磁盘盒由一对上部和下部壳体构成，以便形成硬壳以容纳其中的磁盘。用于将读写头访问磁盘的孔径沿径向方向延伸，该孔被快门选择性地覆盖。壳体在其外围边缘上具有凹槽以接收快门驱动销。凹槽延伸穿过两个壳体构件的相邻表面。由下壳体部件限定的凹槽部分比由上壳体部件限定的剩余凹槽部分更大地扩大，使得快门驱动销不会夹在两个凹槽部分之间的台阶中。

摘要： A disc cartridge capable of effectively preventing a recording surface section of a disc from being directly contacted by an inner surface of a casing. The disc cartridge includes a casing having a space defined therein. An inner surface of the casing has a rear end surface section which is positioned opposite to an insertion side of the disc cartridge and against which a peripheral portion of the disc is abutted. The rear end surface section is formed into a substantially sideways V-shape so that the disc may be positioned at substantially a center of the casing in a width direction of the casing along the rear end surface section.

摘要： A magnetic disk cartridge used for memory means for a computer, which comprises a hard case composed of a cover member and a bottom member, and a magnetic disk having a central hole in which a pivot shaft of disk drive means is inserted. An anti-abrasion chip having a polygon shape including a triangle is attached to the inside of the cover member so as to receive the free tip of the pivot shaft of the disk drive means in contact therewith while the magnetic disk is rotated within the hard case. The shape of the anti-abrasion chip is a regular triangle, a right-angled triangle, an isosceles triangle, a square, a rectangle, a trapezoid or the like. A producing method for a magnetic disk cartridge is also disclosed. The anti-abrasion chip having a polygon shape including a triangle is made by cutting an anti-abrasion sheet attached to a base sheet without causing a disuse portion thereof.
