An optical disc driving apparatus requiring a fewer number of parts, simpler structure, less assembly cost, thus having a lower product price. According to the optical disc driving apparatus, a base plate (200) on which a spindle motor (211) and a pickup unit (213) are mounted is moved to optical disc loading and chucking position together with a caddy (300) by physical force exerted to the caddy (300) inserted into the deck base (100). The base plate (200) is locked by a locking means and positioned. In this situation, an information is recorded and/or reproduced on/from the optical disc. In an ejection mode, the pickup unit (213) is moved in a radial direction of the optical disc so that the base plate (200) is unlocked and is moved to the initial position. Here, the physical force is a pressing force exerted by a user. Accordingly, the optical disc driving apparatus can be compact-sized, and conveniently utilized as a caddy-type as well as a tray-type.

When a second disc is inserted, recording and/or reproducing operation of information on or from a first disc is stopped, and a moving member is moved in the X1-direction. This movement allows a clamp chassis to be moved upward and unclamped, and the second disc is carried into a disc apparatus by a transfer roller and is supported by disc guides. Then, the first and the second discs are supported by the disc guides and are moved upward and then, the first disc is carried out of an insertion opening by the transfer roller. In the course of the movement of the drive chassis to the upper position, the second disc is placed on a turntable, and is chucked and clamped by a clamper. Therefore, it is possible to exchange the second disc with the first disc only by inserting the second disc.

The mechanism for loading and unloading a disk cartridge (13) uses two sliders (70, 73) (one on each side of a base plate (46)), which move in opposite directions under the influence of a tiller (76). Each slider (70, 73) has a slot (262, 281) to receive one of the two lifting pins (136, 139) provided on the cartridge receiver (82). The movement of the sliders (70, 73) drives the lifting pins (136, 139) along the slots (262, 281), thereby raising or lowering the cartridge receiver (82) depending upon the direction of rotation of the tiller (76). The sliding motion of the lifting pins (136, 139) engaged in the S-shaped slots (262, 281) thus unloads a disk (14) from or, alternatively, loads the disk (14) onto the drive spindle (61). As the lifting pins (136, 139) travel along their respective slots (262, 281), the lifting and lowering of the disk (14) is accomplished in such a manner that the disk hub (15) is peeled from the spindle magnet (63) rather than being lifted vertically off the spindle (61). This reduces the peak force required to break the magnetic clamp force between the spindle magnet (63) and the disk hub (15). In this system, the dust door (91) is attached to the cartridge receiver, and the label end of the loaded cartridge (13) remains visible when the disk (14) is loaded. This system may include a bias coil assembly (94) rotatably mounted on an arm (97) so that the bias coil assembly (94) may be loaded into or extracted from the disk cartridge (14) and placed out of the travel path of the disk cartridge (14). The rotation of the bias coil arm (97) is effected by one of the sliders (70, 73).

A cover is moved to an opened position or a closed position at a back side of an opening of a cabinet. A gap in which the cover can lie down is provided between an upper inner wall of the cabinet and a disk holder placed in an insertion completing position of an MD. A first guide groove and a second guide groove, in which a first guide pin and a second guide pin projected in a longitudinal direction from the cover slide, are respectively formed on cover retaining sections provided to both side surfaces of the cover. When each guide pin is guided along each guide groove, the cover draws a substantially arc-like trajectory along the inner wall of the cabinet and enter the gap from an upper end section of the cover. When the cover draws such a trajectory, an opening of a recording and reproducing apparatus into which a recording medium is inserted can be closed by the cover regardless of the case whether or not the recording medium is attached to the recording and reproducing apparatus, and the cabinet of the recording and reproducing apparatus can be small.

An information recording/reproducing apparatus removably holding a disk cartridge including a case having a head window and a recording medium stored in the case is provided. The apparatus includes: a rotation mechanism; a cartridge loading mechanism for transporting the disk cartridge from a first unloading position to a first recording/reproducing position when the disk cartridge is mounted, and for transporting the disk cartridge from the first recording/reproducing position to the first unloading position when the disk cartridge is removed; and a head loading mechanism for transporting the head from a second unloading position to a second recording/reproducing position after the disk cartridge has been placed at the first recording/reproducing position when the disk cartridge is mounted, and for transporting the head from the second recording/reproducing position to the second unloading position before the disk cartridge is transported from the first recording/reproducing position to the first unloading position when the disk cartridge is removed. The second unloading position is set outside the periphery of the disk cartridge at the first recording/reproducing position.

Recording/playback apparatus includes a base 9 with an upwardly biased movable datum locating pin 30. The pin 30 is held down by a lip 205 on a catch 204 to allow a cartridge 8 to be inserted into a tray 70 above the base 9. The edge 14 of the cartridge strikes a tab 201 on an arm 200 and the lip 205 is released from the pin 30 to allow it to be biased into a datum locating hole 10 in the cartridge. A drive plate 80 is then moved in a direction opposite to the arrow A to pivot bell crank levers supporting the tray 70 on pins 41 and 42 to lower the cartridge 8 and engage a contained disk on a spindle therefor. Upon insertion of the cartridge into the tray 70, the pin 30 is released to move into the datum hole 10 in the cartridge when the hole is positioned directly above the pin. The cartridge is then lowered onto the drive spindle and positioned on datum surfaces on the base and pin. During the load cycle, the cartridge is allowed to move relative to the holding tray while continuing to be held in place relative to the base by the datum pin.

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.
