摘要： A disk is manufactured having a reduced capacity based on a quantity of addressable and non-addressable portions. The method of formatting the disk comprises identifying a first quantity of the storage portions; and labeling the first quantity of storage portions as non-addressable storage portions such that the non-addressable storage portions cannot be accessed by a user or a disk drive. The first quantity of storage portions may include addressable portions designated as non-addressable portions.

摘要： Methods are provided for preventing data from being written to a data sector that has been identified as faulty on a disk in a disk drive system. It is first determined whether data of a data sector of a portion of a disk is recoverable. If the data is non-recoverable, an invalid logical ID is written to the logical block address (LBA) corresponding to the data sector thereby identifying the data sector as faulty and preventing data from being written at the data sector. The LBA is then reallocated to point to a different data sector if the data is non-recoverable. Thus, further data directed to the LBA will be written to the different data sector responsive to the reallocated LBA, thereby avoiding writing the new data to the data sector identified as faulty. Internal drive read re-tries can still take place on the faulty data sector even after the LBA has been assigned an invalid logical ID.
摘要翻译：提供了用于防止数据被写入到在盘驱动器系统中被识别为有故障的数据扇区的方法。首先确定磁盘的一部分的数据扇区的数据是否可恢复。如果数据不可恢复，则将无效逻辑ID写入对应于数据扇区的逻辑块地址（LBA），从而将数据扇区识别为故障并防止数据写入数据扇区。然后，如果数据不可恢复，则LBA将被重新分配以指向不同的数据扇区。因此，响应于重新分配的LBA，针对LBA的进一步数据将被写入不同的数据扇区，从而避免将新数据写入被识别为有故障的数据扇区。即使LBA被分配了无效的逻辑ID，内部驱动器读取重试仍然可能发生在故障数据扇区上。

摘要： A defect map for a data-storage medium is generated without the use of a hard index on the medium. The servo sectors normally written to the medium during formatting operations are utilized to identify the angular positions of defective data sectors. The track-location data typically stored in each data sector is used to identify the radial positions of defective sectors. This positional information is processed by a set of computer-executable instructions that generate a graphical representation of the data-storage medium. Symbols are placed on the graphical representation in positions corresponding to the locations on the medium at which defective data sectors are identified.

摘要： Analyzing magnetic media surfaces for thermal erasures and other characteristics is described. The system includes a drive channel module configured to measure servo automatic gain control values for a magnetic media surface that represent the amount of gain applied by the drive channel module to a preamble signal recorded on the magnetic media surface. The gain control values are then acquired according to certain measurement parameters. The gain control values are then arranged by proximity to each other and organized to generate images that represent changes in the characteristics of the magnetic media surface. Analysis of the images then detects patterns that represent changes in the characteristics of the media surface and determines measurement parameters that coincide with the change in the characteristic.

摘要： A track map of a disk drive is generated to compensate for various conditions. A track map is a stored measurement of every “half” servo track width on a disk. Every servo half track width is measured in the factory on a disk and then the data is stored on the disk for use during drive operations. When an individual track is accessed, the appropriate servo half track width data is pulled from memory and is used to adjust a scale factor for that local half track width. The track map may be used to compensate for various conditions including varying servo track width, microjog distance, and data track spacing.

摘要： An apparatus includes a unit that uses a head with spaced read and write portions to write and read information to and from an information storage medium. According to one feature, a desired position for the write element is converted into a position for the read element as a function of a polynomial. According to another feature, the unit uses the head to write and read back selected information in order to determine compensation information, the receiving unit subsequently effecting writing of information with the head as a function of the compensation information. On a more specific level, the unit can removably receive a cartridge that contains the information storage medium.

摘要： An information storage device (10, 510, 610, 710, 810) includes a cradle (12, 512, 612, 712, 812) which can removably receive a cartridge (11, 411, 511, 611, 711) that contains a rotatable hard disk (91, 326-327). A read/write head (107, 331-334) is supported for movement adjacent the disk by a pivotal actuator arm (101). The cradle controls alignment of the head with the disk using feedback servo tracking. Calibration parameters used to perform this tracking, such as servo information or read channel information, may be stored in a special track (414) which is on the disk, and which may be a read-only track. The special track stores a plurality of sets of calibration parameters, each corresponding to a respective combination of a cradle and an environmental characteristic such as temperature. The special track may also be used to store the number of times that the cartridge has been inserted into each of several different cradles, as well as a selected retry method which is more likely than other methods to be successful in recovering data that was subject to errors.
