摘要： A disk apparatus is disclosed. A movable chassis assembly having a turntable and a pickup head is detachably supported on elastic members by a stationary chassis assembly with the lock mechanism of the stationary chassis assembly engaged with lock pins disposed on the movable chassis. A holder located on the movable chassis assembly for holding a disk cartridge to load or eject the disk cartridge is transported by a loader located on the stationary chassis assembly in a predetermined transport direction. Pin driving means located in the loader disengages lock pins when the lock mechanism is touched by the pin driving means at the end of the loading operation of the disk cartridge. A pair of pivoting cross links are connected at their crossings by a support pin that is engaged with a first guide slot in the stationary chassis assembly. One end of each of the pair of cross links is slidably engaged with a guide slot in the loader. The other end of each of the pair of cross links is slidably engaged with a guide slot in the stationary chassis. This arrangement eliminates variations in the load during loading and ejecting operations. A stable operation of the disk apparatus is thus assured. The disk apparatus prevents a double insertion of cartridges and an incorrect insertion, freeing the cartridge and disk apparatus from physical damage.

摘要： A disk recording and/or reproducing apparatus comprises external magnetic field generating means (12) for applying an external magnetic field to a given area of a rotating disk (101) on which informational signals are recorded; means (41) for moving the external magnetic field generating means (12) toward and away from the disk (101) in response to the commencing operation of recording of the informational signals on the disk (101); and means (17) for loading the disk on such a position where the informational signal can be recorded. The moving means (41) is adapted to move said external magnetic field generating means (12) toward the disk (101) only when loading operation of the disk (101) by the loading means (17) is completed. Accordingly, contact of the magnetic head (12) with the disk (101) while the disk (101) is not rotated is prevented.

摘要： A data transfer apparatus for use with a replaceable dislike record medium such as a flexible magnetic disk having data storage tracks thereon, comprising a disk drive motor for imparting rotation to the record medium, and a head transport motor for transporting a transducer head or heads radially of the record medium so as to enable the transducer head or heads to access the individual data storage tracks on the record medium for data transfer therewith. Also included is a control and drive circuit for controllably energizing the head transport motor. When the record medium is not loaded in the apparatus, the control and drive circuit holds the supply voltage of the head transport motor zero. or lower than its normal operating voltage for head transportation, for saving power. Then, as the record medium is loaded into the apparatus, the control and drive circuit applies the normal operating voltage to the head transport motor preparatory to the commencement of data transfer, thereby automatically recorrecting the head position on the record medium.

摘要： A flexible magnetic disk, rotatably housed in an apertured envelope to make up a disk cartridge, is loaded through an entrance slot in the housing of the apparatus to a preassigned position for data transfer with a pair of transducer heads on its opposite sides. Upon subsequent manipulation of a clamp knob, one of the transducer heads is sprung into forced contact with the other transducer heads via the magnetic disk therebetween. In order to avoid the direct contact of the two transducer heads as a result of the user's tampering with the clamp knob when the disk cartridge is not loaded in the apparatus, a head control mechanism is provided for holding the transducer heads away from each other when the disk cartridge is not loaded, even if the clamp assembly is then actuated inadvertently. The head control mechanism allows the one transducer head to travel toward the other for the establishment of data transfer contact with the magnetic disk only when the clamp knob is actuated following the insertion of the disk cartridge in the entrance slot.
摘要翻译：可旋转地容纳在有孔信封中以构成盘盒的柔性磁盘通过设备壳体中的入口槽被装载到预分配位置，用于在其相对侧上具有一对换能器头的数据传送。在夹持器的后续操作中知道，其中一个换能器头经由其间的磁盘被弹簧与另一个换能器头部强制接触。为了避免当盘盒未被装入设备时由于用户对夹具旋钮的篡改而导致两个换能器头的直接接触，提供了一种头部控制机构，用于将换能器头彼此远离地保持，即使夹紧组件无意中被启动，磁盘盒也不会被装载。头部控制机构允许一个换能器头朝着另一个传感器头移动，以便仅当在将盘盒插入入口槽中之后启动夹紧旋钮时才建立与磁盘的数据传送接触。

摘要： When a user requests a reproduction operation via a remote control, a microprocessor determines whether or not data on a medium of the type selected in advance by a user using the remote control can be reproduced. When the microprocessor determines that data on a medium of the selected type can be reproduced, it selectively reproduces data on the medium of the selected type. When the microprocessor determines that data on a medium of the selected type cannot be reproduced, it sequentially determines whether data on media other than media of the selected type among multiple types of media can be reproduced or not, sets the type of a medium on which data can be reproduced, which is found as a result of the determination, as the type of media to be played, and reproduces data on the medium on which data can be reproduced.

摘要： An optical disc drive (2) for optical discs (9), comprises a retractable disc tray (1) with an opening (3) and a tray base (33) on which a disc (9) with non-circular shape can be placed and centered by a user when the tray (1) is in a deployed position. A shaft (30) with drive plate (31) and centering pin (32) is able to rotate the disc (9) when the tray (1) is in a retracted position during operation of the drive (2). The drive comprises first means (25, 27) arranged on the shaft and second means (26, 28) arranged around the shaft, the first means and the second means being able to interact with each other, and to stop the rotating shaft (30) in a predefined end position. Alternatively the drive (2) comprises means (11, 12, 14, 15) for determining the relative orientation of the disc (9) with non-circular shape in relation to an absolute rotation angle of the shaft (30) bearing the disc (9), in order to enable the drive (2) to rotate the shaft (30) with disc (9) into a position, in which the tray can be safely deployed.
