Abstract: PURPOSE:To realize the brake action for a motor for improving the stopping precision in a tape stop section at the time of slow reproducing a VTR belt- driving a tape reel system or the like without deteriorating responsiveness and with a reduced cost. CONSTITUTION:A reverse rotation by the tension of a belt is stopped without using a mechanical brake by applying a voltage value of an extent where no capstan motor is started to rotate to the capstan motor 2 in the tape stop section at the time of slow reproducing or the like, and the stopping precision of a magnetic tape is improved. The dispersion in a mechanical load is compensated by measuring the current value of the capstan motor 2 in a reproducing section by a measuring means 14 and applying the applied voltage value at the time while giving feedback by a control means 13. By such a manner, the brake action for the capstan motor 2 is realized without depending on the mechanical operation, and a cost is suppressed, and the responsiveness at the time of variable-speed reproduction is improved.

Abstract: PROBLEM TO BE SOLVED: To improve access time.SOLUTION: An recording and/or reproducing apparatus comprises a disk storage table 3, disk drive parts 4A and 4B, mechanical chassis 5, drive shifting parts 6A and 6B, and a disk transfer part. The disk storage table has a plurality of disk housing parts capable of storing a disk 2. The disk 2 is detachably loaded in the disk drive part, and the disk drive part is able to record and/or reproduce an information signal for the loaded disk. The mechanical chassis supports the disk housing table such that the table is freely rotated, and supports the disk drive part such that the drive part is movable. The drive shifting parts brings the disk drive part close to the disk housing table and separates the disk drive part from the disk housing table. The disk transfer part transfers the disk between the disk detaching position of the disk loading part, from which the disk in the disk drive part is detached, and the disk housing position of the disk housing part, in which the disk is housed.

Abstract: PROBLEM TO BE SOLVED: To provide a hard disk device capable of eliminating the necessity of providing an area dedicated for the installation of a magnetic head on a magnetic disk, preventing the generation of very small dusts, simplifying a structure to reduce costs, and preventing the possibility of the breaking of the magnetic head and the magnetic disk. SOLUTION: A supporting member 70 is bent in a width direction orthogonal to a longitudinal direction by simultaneously elongating one of two second actuators 70 and shortening the other, and thereby displacement or vibration is generated in a direction orthogonal to the longitudinal direction of a supporting member 50. When the smooth surface of a magnetic head 40 facing a recording surface 3002 is adhered to the recording surface 3002, the magnetic head 40 receives a force in a width direction orthogonal to the longitudinal direction of the supporting member 50 within a plane substantially parallel to the recording surface 3002 of a magnetic disk 30 by the elongating/contracting operation of the second actuators 70, and sticking between the magnetic head 40 and the recording surface 3002 is forcibly released.

Abstract: PURPOSE:To provide a power transmission switching mechanism which can operate without being damaged even when tips of teeth of the respective gears mutually interfere. CONSTITUTION:The transmission gear 12 is supported at the central part 11a of a switching arm 11 so as to be freely rotated by a shaft 3. Simultaneously, the switching gear 13 is supported at the tip part 11b thereof so as to be freely rotated by a supporting shaft 14. On the side of a slide plate 15 on the tip part 11b side, an engagement part 11e made to abut or separated on/from the projection 15c of the plate 15 is integrally formed. Besides, a U-shaped notched groove 11d is obliquely formed on the central part 11a side from the engagement part 11e. A tension coil spring 16 is interposed between the stopper part 11c of the base part of the arm 11 and a shaft 4. Thus, when the tips of the teeth parts 10a and 13a of the respective gear 10 and 13 mutually interfere, the tip part 11b side of the arm 11 is elastically deformed in a direction that it is separated from the driving gear 10 and the teeth parts 10a and 13a of the respective gears 10 and 13 are not damaged among themselves.

Abstract: PURPOSE:To miniaturize a device and to simplify the structure of a switch mechanism by securing the interlocking between the transmission bars of a transmission disk and the coupling holes of the output and input disks by means of a torque switch means and giving the reciprocating movements to the transmission disk between the 1st ad 2nd positions. CONSTITUTION:When a transmission disk 6 is moved to the 1st position by a torque switch means 7, the transmission bars 19 of the disk 6 interlock the coupling holes of both input and output disks 1 and 5 respectively. The drive torque supplied to the disk 1 is transmitted directly to the disk 5 via the bars 19. Then the disk 6 is shifted to the 2nd position by the means 7 and the interlocking state is released between the bars 19 and at least one of both coupling holes of disks 1 and 5. Thus it is possible to transmit the drive torque to the disk 5 from the disk 1 via a frictional torque transmission means not via the bars 19. This keeps the output torque at a fixed level of less. As a result, the reciprocating movements of the disk 6 is secured by the means 7 toward the axial line of the disk 6. Thus the output torque can be switched.
