摘要： A disc apparatus has a cartridge loading/unloading mechanism to perform a loading operation for attaching an optical disc enclosed in a cartridge inserted from an outside to a rotary shaft of a spindle motor and an unloading operation for removing the optical disc from the rotary shaft of the spindle motor and for ejecting the cartridge to the outside. The loading operation of the cartridge loading/unloading mechanism is executed by the rotation of one direction of a load motor. The unloading operation of the cartridge loading/unloading mechanism is executed by the rotation in the reverse direction of the load motor. A drive current of the load motor is turned on or off at a short period, thereby adjusting so as to optimize a drive torque. When an exchangeable optical disc is loaded, a motor is activated, an initialization control is executed during the acceleration, and after a motor rotational speed reached a specific speed, the apparatus enables the writing/reading operations to be executed. When a voice coil motor is driven simultaneously with the spindle motor during the initialization adjustment, the drive current of the spindle motor is limited.

摘要： An optical disk apparatus adapted to a mark edge recording method having a structure such that a data pattern experimentally recorded on an optical disk with one write power is reproduced plural times while changing reproducing conditions (for example, a slice level for binary-coding a reproduced analog signal) and the number of errors is calculated whenever the reproducing process is performed. The thus-structured process is repeated for using a plurality of write powers. An appropriate write power for the optical disk is determined in accordance with the obtained results of the calculations of the number of errors. In a case of a read-only optical disk, a data pattern experimentally and previously recorded on the optical disk is reproduced plural times by changing the reproducing conditions (for example, a slice level for binary-coding a reproduced analog signal), and the number of errors is calculated whenever the reproducing process is performed. In accordance with the obtained results of the calculations of the number of errors, an appropriate reproducing condition for the optical disk is determined.

摘要： A storage apparatus rotates an optical recording medium at two or more kinds of rotational speeds. The rotational speed is decreased when a read or write margin becomes less than or equal to a first predetermined value or, when a frequency of generation of a servo abnormality of a tracking servo and/or a focus servo is greater than or equal to a first predetermined frequency. On the other hand, the rotational speed is increased when the read or write margin becomes greater than or equal to a second predetermined value or, when the frequency of generation of the servo abnormality of the tracking servo and/or the focus servo is less than or equal to a second predetermined frequency.

摘要： An objective lens of an optical head is cleaned with a cartridge accommodating a cleaning disk with a brush thereon. The cleaning disk is rotated in apparatus to clean the surface of objective lens provided on the optical head. Simultaneously with causing the rotation of the cleaning disk by driving a spindle motor, the lens is moved toward and away from the disk by driving a lens actuator. Additionally, simultaneous reciprocation of a carriage carrying the optical head toward alternate inner and outer disk peripheries may be caused. Further, the operation of reciprocating the objective lens toward the inner and outer disk peripheries and the operation of moving the lens toward and away from the cleaning disk with the lens actuator may be performed in combination.

摘要： A division test write processing unit is provided and a test writing process for deciding an optimum light emitting power by executing a test writing on a medium is divided into a plurality of division test writing processes. When an upper command is received, in the division test write processing unit, a division control unit skips to a division executing unit locating at the head of the processes which are not yet executed among a plurality of division executing units and allows the dividing processes of the test writing to be executed for a predetermined time.

摘要： An apparatus for reading at least information by projecting a light beam from an optical head onto an optical disk rotated by a spindle motor. The rotation time of the spindle motor is measured, and upon reaching of a predetermined time, a cleaning request signal is sent to an upper order system. The rotation time of the spindle motor is counted by counting pulses generated with the rotation with a first counter stored in the RAM. Upon reaching of a predetermined value by the count of the first counter, a second counter stored in a non-volatile memory is updated. Upon reaching of a predetermined value by the second counter, a cleaning request is sent to the upper order system for display on a CRT, and a cleaning request flag in a non-volatile memory is set. When the end of cleaning of the apparatus is recognized, the cleaning request flag in the non-volatile memory is cleared.
