摘要： A disc cartridge made of two molded plastic shells, joined together. Each of the shells have portions of differing molding shrinkage. In an annular embodiment, the outer annulus has the smaller molding shrinkage. In a planar embodiment, the exterior layer has the smaller molding shrinkage. The differing contractions causes the shells to bend outward, away from the enclosed disc.

摘要： A magnetic recording disk having a rigid substrate disc is provided with an annular air gap defined between inner and outer peripheral bonding rings. A flexible disc sheet having a recording surface is placed over the arrangement and held tight against the peripheral bonding rings while the inner and outer edges of the flexible disc sheet are bonded to the bonding rings. In order to avoid deformation of the recording surface due to thermal expansion of the air trapped in the gap, the substrate is made porous to provide air passages between the air gap and the external atmosphere.

摘要： A magnetic disk cartridge containing a floppy magnetic disk is provided with center core which has a groove where the vertical part of the core meets the flange upon which the disk is fastened by a double-sided adhesive ring. This groove can accommodate a portion of the adhesive ring which is positioned out of true. This ensures that such misalignment does not cause deformation of the disk and the deterioration in read/write performance with the disk. The groove also serves to prevent flange flashing from scraping fragments off the inside of the cartridge wall, and the possible harm such fragments cause if they stick to the disk.
摘要翻译：包含软磁盘的磁盘盒设置有具有凹槽的中心芯，其中芯的垂直部分与通过双面粘合环固定该盘的凸缘相接合。该凹槽可以容纳位于真实位置的粘合环的一部分。这确保了这种不对准不会导致盘的变形和盘的读/写性能的劣化。凹槽还用于防止法兰从墨盒壁内部刮掉碎片闪光，并且如果它们粘附在盘上，可能会造成伤害。

摘要： A magnetic tape cassette intended for applications such as digital recording where extremely tight tolerances are imposed on the amount of widthwise deviation of the tape. A partition member, dividing the cassette into a recording and reproducing region and a tape winding core accommodating region, is molded separately from the two halves of the shell of the cassette. The partition member has a partition wall having guide walls protruding forwardly therefrom symmetrically with respect to the center line of the cassette. The pair of guide walls closest to the center line have front portions of reduced height so that the upper and lower portions thereof do not contact the cassette halves.

摘要： A magnetic disk cartridge has a case, a magnetic disk rotatably housed in the case, a cleaning liner positioned between the magnetic disk and an inner wall surface of the case facing the magnetic disk and extending at least from an inner edge portion to an outer edge portion of the recording area of the magnetic disk, and a lifter positioned between the inner wall surface of the case and the liner. One end portion of the lifter is secured to the inner wall surface of the case, and the other end portion of the lifter is raised obliquely from the inner wall surface of the case to form a rising portion which pushes up the liner and makes the liner uniformly contact the magnetic disk over the area from the inner edge portion to the outer edge portion of the magnetic disk. The lifter is subjected to heat setting when the rising portion is formed.

摘要： A magnetic disk cartridge comprising a magnetic disk for conducting image recording and reproducing through high-speed rotation and a case having a magnetic head receiving hole near a diagonal line of the case is provided with a shutter member having a rotation center at the corner of the case nearest to the magnetic head receiving hole. The shutter member is rotated fanwise to open and close the magnetic head receiving hole. The magnetic head receiving hole is opened when a portion of the shutter member engages an exterior shutter opening contact member of a recording device upon insertion of the magnetic disk cartridge. The magnetic head receiving hole is closed upon removal of the disk cartridge from the recording device.
