摘要： A method of changing a program for controlling a disk drive that includes an EEPROM. The method includes storing a program block to a disk area such that the program block is associated with a second area for storing the program block that is not utilized for a read operation from the disk area. The method also includes storing a program block that is associated with a first area to an area that includes at least a portion of the second area in the EEPROM such that the first area contained a program block that is utilized for a read operation from the disk area. In addition, the method includes changing the program block in the first area after storing to the second area. Moreover, the method includes storing to the second area the program block that is not utilized for a read operation from the disk area after storing to the first area.

摘要： Embodiments of the invention improve utility of a magnetic disk drive in which a head is retracted if the magnetic disk drive is in a dropping state. In one embodiment, an HDC/MPU provided in a magnetic disk drive judges whether the magnetic disk drive is in a dropping state based on an output from an acceleration sensor which may detect an acceleration and performs a retraction operation of a head. After the HDC/MPU judges that a drop is occurring, the HDC/MPU detects whether the drop judgment is incorrect according to whether a shock sensor detects a shock occurrence and changes the drop judgment condition based on a detection history of detected incorrect judgments.

摘要： 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.

摘要： 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.

摘要： Embodiments in accordance with the present invention help a disk drive to effectively cope with a data address mark detection error. In one embodiment, a data sector is provided with plural data address marks and an read/write (RW) channel reads out the data sector using part of those data address marks. Each divisional section of a split sector has two data address marks and the RW channel uses one of the two data address marks. A data address mark to be used is specified by a register. When an error occurs in detecting a data address mark, its position is stored in a register. Based on the error position, an error recovery processing section stores, in the register, a data address mark to be used in a next retry.

摘要： A recording medium has a first area in which data encoded with a first error correction code is recorded and a second area in which data encoded with the first error correction code and data decodable with a second error correction code that is different from the first error correction code are mixedly recorded. Data that causes the cumulated value of a DC component per unit period of data reproduced from the second area to deviate is recorded in the second area.

摘要： Embodiments of the invention provide an interface circuit that is capable of reducing the power consumption, which may be increased by a shoot-through current, and provide an electronic device having such an interface circuit. In one embodiment, an interface circuit exchanges signals with another electronic device via a signal transmission line. The interface circuit includes a switch for pulling up the signal transmission line and a switch for pulling down the signal transmission line. While a pull-up or pull-down is performed, the interface circuit detects the potential level of the signal transmission line to determine whether the signal transmission line is pulled down or pulled up by the other electronic device. If the signal transmission line is not pulled down/pulled up by the other electronic device, the interface circuit exercises pull-down/pull-up control.

摘要： An image processor containing an EPROM (38) stored with coefficient data for image enlargement and reduction, coefficient read controllers (40-44) for reading out coefficient data from the EPROM (38) according to an enlargement/reduction selection signal, a variable horizontal characteristic filter (16) for executing either image enlargement or image reduction according to the coefficient data, a variable vertical characteristic filter (18) also for executing either image enlargement or image reduction according to the coefficient data, a frame memory (20), a contour correcting circuit (14), and selectors (22-30). When image enlargement is selected by selectors (22-30), input video signals are processed by the contour correcting circuit (14), the frame memory (20), and the filters (16,18) in this order while, when image reduction is selected, input video signals are processed by the same in the reverse order. The portion which should not undergo contour enhancement does not undergo contour enhancement during image enlargement, and high frequency components enhanced by contour correction during image reduction do not disappear and adequate contour correction, even when either processing image enlargement or reduction, is selected.

摘要： A method and apparatus for relocating the data in defect sectors having occurred in the storage medium of an information recording and reproducing apparatus is described. If a defect occurs in a sector of a user area, the data of it is relocated to a temporary storage area. The logical block addresses (LBA's) for a group of sectors including an alternate sector are sequentially reassigned by skipping the defective sector and including the alternate sector. Data in the group of sectors are read out from the rear part of the user area according to current LBAs, and written according to new LBAs. Since the addresses of new LBAs are smaller than those of current LBAs by the number of defect sectors, the original data is not destroyed in the writing.
