摘要： A disc cartridge capable of preventing a recording surface section of a disc from being contacted by a casing and placing the disc at a proper position in the casing without damaging and polluting, to thereby ensure the safe and smooth operation of the disc in the casing. The disc cartridge includes a pair of disc receivers each of which is formed therein with a recess for receiving a peripheral portion of the disc. The recess has an end surface contacting an outer periphery of the disc, which is formed into a substantially sideways V-shape of which an apex is positioned at substantially a center of the end surface to position the outer periphery of the disc at the center of the end surface.

摘要： A tape cassette has a case with upper and lower halves and an open space at the front thereof. A magnetic tape housed in the case is wound around a pair of reels. A brake is slidably mounted on the inner surface of the lower half of the case to prevent the reels from being rotated. Part of a spring is attached to the brake. The spring has free ends and urges the brake in a direction. A device for positioning the spring includes a partition wall on the inner surface of the lower half of the case which partitions the open case from the inside of the case. An independent abutment member on the partition wall abuts the free ends of the spring.

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 tape cassette has a housing and a pressure pad apparatus mounted within the housing for bringing a magnetic tape into direct contact with a magnetic head. The pressure pad apparatus includes a pad, a spring joined to the pad for imparting a pushing force to the magnetic head, and a holding member mounted within the housing for holding the spring at two points spaced from each other. The effective length of the spring is greater than the distance between the two holding points of the holding member.

摘要： A disc cartridge capable of ensuring its stable and positive operation without damaging a disc while satisfactorily producing a cleaning effect and maintaining adequate contact between the head of a cartridge operating unit and the disc. Each of a pair elastic members respectively mounted on the upper and lower inner surfaces of a casing forcibly presses a sheet-like liner situated between the elastic member and a disc against the disc through a projection portion having a predetermined length formed as part of the elastic member, resulting in the liner contacting the disc with a force at substantially a constant level for a long period of time.

摘要： A disc cartridge capable of preventing a recording surface section of a disc from being contacted with an inner surface of a casing so that the disc may be free from any damage. The disc cartridge includes steps or sheet-like members provided on the inner surface of the casing in a manner to be inwardly projected from the inner surface. The steps or sheet-like members are positioned so as to be engaged with a non-recording surface section of the disc to support the disc thereon, so that a clearance may be defined between the recording surface section of the disc and the inner surface of the casing.
