Abstract: PROBLEM TO BE SOLVED: To prevent the generation of various problems during the positioning of a cassette to a bent mandrel by making the cassette easy to position to the bent mandrel in a magnetic tape cassette device. SOLUTION: In the magnetic tape cassette device provided with a tape deck which is constituted of the bent mandrel 5 freely rotatably supported with a bearing spindle 3, the mandrel 5 is suitable for fitting into a center hole 13a of the cassette and composed of a connecting fin 10a arranged around it. The bent mandrel 5 is mounted on the bearing spindle 3 so as to be movable in the axial direction within the moving area in the axial direction, and it is preliminarily loaded toward the appropriate position in the axial direction by at least one spring 9.

Abstract: PROBLEM TO BE SOLVED: To provide a device for a deck for playing back an information disk which removes play in the axial direction and the radial direction of a motor. SOLUTION: An information disk 2 is rotated around a rotary shaft 3 by a drive motor 5 during operation. Material parts 8 and 9 which cooperate magnetically are offset in a radial direction to the rotary shaft, and are parallel in the direction with each other. One material part 8 is installed on a base plate 4 holding the motor. The other material part 9 is installed on a disk supporting base 1 to be moved by a shaft 6. In the device which is a ring-shaped permanent magnet, at least one of the two material parts 8 and 9 which cooperate magnetically is eccentrically arranged to the rotary shaft. The device is characterized by that both material parts are ring-shaped, and the linear direction of the fields does not change during rotation.

Abstract: PROBLEM TO BE SOLVED: To reduce the vibration clearance by providing a spring arrangement having progressive spring characteristic on a damping means. SOLUTION: This structural unit 2 is connected to a housing 1 by a spring arrangement 3. Each spring arrangement 3 is provided with a cylindrical coil spring 4. The cylindrical coil spring 4 has a coil part having a nonlinear space, and consequently has progressive spring characteristic in the longitudinal axial direction. Since the progressive vibration damping to vibration amplitude is caused by the spring arrangement 3 and its progressive spring characteristic, the spring arrangement 3 has progressive spring characteristic entirely in all three directions in a space. Thus, the vibration amplitude of the lowest vibration frequency having an influence on the volume of a mounting position is reduced, whereby the vibration clearance S is reduced. Accordingly, the volume of the entire mounting position of the housing 1 is reduced.

Abstract: PROBLEM TO BE SOLVED: To remove a prescribed inclination error by installing an adjusting device for adjusting a lens unit for adjusting the optimum angle of a lens unit on a turning recording medium on a turn table. SOLUTION: In an optical scanning unit 6 provided with a lens unit 8 supported so that it can be adjusted, the lens unit 8 has an output lens in the center and the system of a coordinate x-y-z is installed in the center of the output lens 9. The lens unit 8 can turn around an x-axis by a second adjusting screw 11 so that an angle θJ can be adjusted. The angles θR and θJ are generated between the actual radiation direction of a laser beam turned to a recording carrier and the optimum radiation direction of the laser beam. The optimum radiation direction can be adjusted by turning the lens unit 8. A jitter value depending on the angle is used as the measurement reference of the adjustment of the lens unit 8.

Abstract: PROBLEM TO BE SOLVED: To provide an information disk changer device having a compact structure. SOLUTION: This changer device is constructed in such a manner that each of holding trays 16 to 20 has two portions, i.e., top portions 16a to 20a and bottom portions 16b to 20b, the top portions 16a to 20a and the bottom portions 16b to 20b are integrally movable in the same direction by a first transport mechanism 30 for transporting an information disk 3 in a stacking unit, and the top portions 16a to 20a and the bottom portions 16b to 20b of the holding trays 16 to 20 for holding the information disk 3 targeted for reading and/or writing are movable in relative relation by the first transport mechanism 30 so as to bring the information disk 3 to a playing position for reading and/or writing. Thus, a gap is formed between the information disk 3 and the top portions 16a to 20a and/or between the information disk 3 and the bottom portions 16b to 20b.

Abstract: PROBLEM TO BE SOLVED: To position a disklike information carrier more in the radial direction on a turntable by applying a radial clamp member so that it engages the internal wall of a positioning hole of the disklike information carrier and an axial clamp member so that it engages the radial surface of the disklike information carrier. SOLUTION: A spring 6 is arranged on the peripheral surface of a conic centering mandrel 5. A pressure part 7 which is arranged on the centering mandrel 5 is able to move toward the center positioning hole 4 in a negative direction Z through an actual mechanism. Consequently, the spring 6 is also operated by a projection part 7a of the pressure part 7 and is able to move toward the center positioning hole 4. For the axial fixation of the disklike information carrier 2, an axial pressure disk 8 is provided. The pressure disk 8 has a clamp surface 8a operating on the radial surface 2a of the disklike information carrier 2.

Abstract: PROBLEM TO BE SOLVED: To install a damper by a simple and highly reliable method by connecting a base part to an integrated fixing element by an elastic cover part. SOLUTION: A damper 1 is formed of a cylindrical base part 2, an elastic cover part 3 for shutting it off, and a fixing pin 4 as fixing element, and the base part 2 and the cover part 3 surround a cavity 5 filled with oil. The fixing pin 4 is positioned in the center of the cover part 3, the inside part 4a is extended to the cavity 5, and the outside part 4b is extended across the cavity 5 and the cover part 3, so that the fixing pin 4 is connected to the elastic cover part 3 in the axial central region 4c. The base part 2 and the fixing pin 4 are made of a hard and nonelastic synthetic material, and the damper 1 is manufactured by a multiple parts molding method. Because the fixing pin is integrally formed with the base part and the cover part, the damper can be installed by a simple method and dispenses with the another installation of the fixing pin and the damper.

The method comprises the steps of: deriving from said read signal (SR) at least two signals (REn; MIRn) of mutually different type; and varying the setting of said at least one variable control parameter as a function of said at least two signals. An other method is described for discriminating two kinds of disturbances originated by a) disc defects, b) schocks.
