Abstract: When a host apparatus transfers/swaps stored information between user sectors in a storage device for the purpose of defragmentation or the like, the storage device is allowed to perform the data transfer or swap without transmission between the host apparatus and the storage device after the command is received by the storage device; and consistency in stored information identification is maintained between the host apparatus and the storage device even if the operation is interrupted. In one embodiment, information stored in the destination user sector LBA(Y) is copied to the dummy sector LBA(D), its entry is written in the mapping table RDM, information stored in the source user sector LBA(X) is copied to LBA(Y), and then the RDM entry is erased.

Abstract: A file is transferred directly between a parent magnetic-disk device and a child magnetic-disk device. In one embodiment, a parent magnetic-disk device has a host-mode execution program, whereas a child magnetic-disk device is capable operating in a device mode as is the case with an ordinary magnetic-disk device. The parent magnetic-disk device has an operating-mode-setting unit including a special-purpose jumper block. An MPU employed in the parent magnetic-disk device executes the host-mode execution program to put the parent magnetic-disk device in a host mode. At an activation time, the MPU refers to the logic of the special jumper block to start an operation in the host mode. The MPU controls the parent magnetic-disk device to directly transfer a file to the child magnetic-disk device. Thus, the file can be transferred between the parent and child magnetic-disk devices without intervention by a host computer.

Abstract: Embodiments of the invention control a recovery procedure effectively in accordance with write conditions. In one embodiment, the data to be written into a sector includes not only user data but also recording condition data, which indicates the temperature prevalent during a write. If a data read is not accurately performed, a recovery procedure is executed. If a data read is accomplished by a retry and the temperature prevalent during a write is lower than predetermined, it is concluded that the employed medium is nondefective. Thus, the read data is rewritten into the same sector without being stored in a spare area. This prevents the spare area from being unnecessarily consumed.

Abstract: An offset component extracting circuit is supplied with a tracking error signal TE' obtained by using the push-pull method and including an offset component resulting from optical axis deviation, etc. of the object lens followed by tracking. The offset component extracting circuit extracts, from the tracking error signal TE', an offset component included in the tracking error signal itself. A hold circuit outputs offset component S1 delivered from the offset component extracting circuit as offset component S2 as it is for a time period during which servo is in OFF state on the basis of a servo command signal delivered from a system controller to hold the offset component S1 when servo operation changes from OFF state to ON state to output the offset component S1 thus held as offset component S2. A differential amplifier subtracts the offset component S2 from the tracking error signal TE' to deliver a tracking error signal TE from which the offset component S2 has been eliminated to a tracking control circuit through a switch 15. The tracking control circuit includes, e.g., a phase compensation circuit, etc. in the servo control, and drives, e.g., biaxial device of the optical pick-up on the basis of the tracking error signal TE delivered thereto. Thus, tracking servo is applied so that spot of light beam is placed in on-track state.

Abstract: A tracking control apparatus of an optical disc apparatus capable of preventing unstability of the tracking control due to the deviation of balance of a tracking error signal due to a movement of the field of vision of an object lens. A hysteresis tracking error signal is generated by masking a signal of a half cycle of an off-track state of a tracking error signal at the time of a high speed feeding of a sled and the tracking servo control is carried out by using this signal. Namely, with respect to a tracking error signal calculated at a tracking error calculation circuit, a transistor is turned off by an inverted ENABLE signal indicating the state immediately after the high speed feeding of sled, thereby to make the mirror signal valid, the transistor is turned on when this mirror signal is at a high level indicating the detrack state, a hysteresis tracking error signal obtained by reducing the tracking error signal to the ground level is generated, and the tracking servo control is carried out by using this signal. The component of deviation of the tracking error signal due to the movement of the field of vision of the object lens is reduced to a half, therefore the oscillation of the tracking servo control due to an increase of the accumulation of error can be prevented.

Abstract: When writing user data D, the user data D is stored in a register 46, and using both the user data D and the sector information (ID) of the user data D, an error correction code ECC is generated by an ECC generation algorithm Ar. A stored information Rw made up of the user data D and the generated ECC is written on a disk. In the reading, the user data Dr of a read record Rr is temporarily stored in the register 46, and an ECC check algorithm is executed. This ECC check is executed for combined data of the user data Dr and its position information. When any error is found in the position information portion in the combined data, the user data is determined that the read user data is wrongly addressed. When an error is found in the user data Dr portion, the user data is corrected by ECC and the corrected user data is output.
