摘要： A disk cartridge has a disk accommodated in a casing having a center aperture and access windows. A pivotal shutter is pivotally mounted for closing the center aperture. A rotary shutter is rotatably mounted for closing the access windows and interlocked with the pivotal shutter. A first slidable member is cooperatively coupled to the rotary shutter, and a second slidable member is opposed to the first slidable member and adapted to be slid upon engagement with a shutter actuating member when a disk drive is loaded with the disk cartridge. The first and second slidable members having racks on their opposed surfaces interlocked through a gear mechanism for transmitting the motion of the second slidable member to the first slidable member, which in turn, drives the rotary shutter.

摘要： A disc cartridge capable of permitting a hub to be constantly rotated about the center of rotation thereof without any eccentricity, to thereby ensure smooth and stable rotation of the disc. The hub is formed with three drive shaft inserting holes in a manner to be spaced from each other at equal intervals and positioned on a concentric circle of a predetermined radius defined about a center of rotation of the hub. The drive shaft inserting holes each are formed with a linear driven surface which is adapted to be contacted with a drive shaft inserted into the hole. The driven surface may be arranged at an angle of -30 to +30 degrees with respect to the center of rotation of the hub.

摘要： An elastic lifter arranged on an inner surface of a casing of a disc cartridge to exert a pressing force on a disc is formed integrally with the casing and into a plate-like shape in such a manner that a proximal end thereof is connected to the casing and a distal end thereof is rendered free. Such construction permits the pressing force to be kept constant for a long period of time and effectively prevents damage to the disc, to thereby substantially improve durability and reliability of the disc cartridge while significantly decreasing the number of parts, facilitating assembling of the disc cartridge, and attains a decrease in manufacturing cost. The lifter may be formed at a proximal end thereof with a decreased thickness, to thereby facilitate bending of the lifter.

摘要： A disc cartridge capable of preventing entering of dust into a casing and ensuring a stable and positive operation without damaging a disc while satisfactorily exhibiting a cleaning effect and keeping proper contact between a recording head and the disc. A casing is provided thereon with a slide area which is formed by a slide area defining section of the casing. The slide area is formed with at least one head inserting hole. The slide area defining section is provided on an inner surface thereof with at least one thick-walled portion in a manner to extend along a whole periphery of a portion of the head inserting hole overlapping a sheet-like liner and inwardly project from the inner surface of the casing, so that the liner may be pressed against the disc at a force of a constant level over a wide area of the disc and block a communication between an exterior of the cartridge and its interior through the head inserting hole.

摘要： A disc cartridge and a casing therefore capable of carrying out insertion and removal of a disc with respect to the casing without separating a shutter from the disc cartridge and adversely affecting the disc, with simple operation. The casing includes a casing body constituted by an upper cover member and a lower cover member joined together to form an inner space therein which is adapted to rotatably receive therein a disc having a non-recording section formed at its outer periphery and be separable at rear ends thereof from each other. The casing also includes a pair of guides arranged on both side of a rear portion of an interior of the casing body so as to be opposite to each other. The guides permit insertion and removal of the disc with respect to the casing body to be safely accomplished along the guides through the opened rear end of the casing. The disc cartridge uses such a casing.
