摘要： A method, apparatus, and article of manufacture for determining a transducer position in relation to a media surface is described. The method comprises sensing positioning information on the media, measuring a position error signal from the sensed positioning information wherein the position error signal includes first and second position signal components, accessing stored information describing a non-linear relationship between the measured position error signal and the transducer position, and applying the stored relationship to the measured position error signal to produce a corrected position error signal, and determining the transducer position from the corrected position error signal.

摘要： A method, apparatus, and an article of manufacture for calibrating a position error signal for controlling the position of a read transducer with respect to a storage media having positioning information written at a location thereon. In one embodiment, the invention is embodied in a method comprising determining a relationship between a read transducer position and the positioning information by measuring the positioning information while passing the read transducer across the location, determining a measured position error signal from the measured positioning information, and computing a relationship between the measured position error signal and the read transducer position.

摘要： A data recording disk drive includes a system and method for mapping around skip sectors, both bad sectors and spare sectors. A received logical block address is converted to a corresponding physical block address by mapping through a set of tables. A first table includes entries for virtual tracks which group together LBAs having shared high order bits. A second table contains entries for the skip sectors. The high order bits of a given LBA are used to select an entry in the first table, which entry is an index into the second table. Starting from the index point, the second table is searched, using the low order bits of the LBA, for a skip sector beyond the LBA value. Once the appropriate skip sector is found, the index of this skip sector within the second table is added to the LBA to compute the PBA. The PBA is then mapped to a zone, cylinder, head, sector location on the disk drive. The mapping system reduces the total storage required to convert LBAs to ZCHS values and improves the performance of the conversion process. Additional features include a third table for distinguishing bad sectors from spare sectors, schema for re-mapping spare sectors to substitute for data sectors which fail during use, and overlap between the LBA high order and low order bits to further improve performance.
摘要翻译：数据记录盘驱动器包括用于在不同扇区和备用扇区两者周围映射的系统和方法。通过映射一组表，接收的逻辑块地址被转换为相应的物理块地址。第一表包括用于将具有共享高阶位的LBA组合在一起的虚拟磁道的条目。第二个表包含跳过扇区的条目。给定LBA的高位用于选择第一表中的条目，该条目是第二个表中的索引。从索引点开始，使用LBA的低位来搜索超出LBA值的跳过扇区的第二个表。一旦找到适当的跳过扇区，则第二个表中的该跳过扇区的索引被添加到LBA以计算PBA。然后将PBA映射到磁盘驱动器上的区域，圆柱体，磁头，扇区位置。映射系统减少了将LBA转换为ZCHS值所需的总存储量，并提高了转换过程的性能。附加功能包括用于区分不良扇区与备用扇区的第三个表，用于重新映射备用扇区以替代在使用过程中失败的数据扇区的模式，以及LBA高阶和低位之间的重叠，以进一步提高性能。

摘要： A reassign process is provided in a disk drive system including a plurality of tracks for storing data, each of the tracks being divided into a plurality of sectors, each sector having a corresponding logical address value associated therewith. Each track has a corresponding skew associated therewith and having a nominal skew value providing adequate time for sequential access of the corresponding track from a sequentially preceding track. The reassign process is operative to reassign data sectors stored in a reassign span including a first partial track having a reassign sector, a second partial track having a spare sector corresponding with the reassign sector, and at least one intermediate track disposed between the first and second partial tracks. The reassign process includes adjusting the nominal skew value of at least one of the intermediate tracks by a corresponding skew delta adjustment value so that the logical address values associated with the sectors of the intermediate track are transposed thereby effectively shifting data stored in selected sectors of the intermediate track in a direction of the spare sector relative to the reassign sector.
