摘要： A zoned recording, embedded servo disk drive includes a sector architecture in which the recording head locates and identifies data sectors without using data identification (ID) fields, but instead using information obtained from electronic storage and from servo sectors which need not be adjacent to the data sectors. Each data track contains servo information and data, but not data sector ID information, and is circumferentially divided into identical segments. Included in each track segment is a number of data regions separated from one another by servo sectors. The data regions in each track segment may contain partial data sectors and complete data sectors, and each data sector is identified by a number indicating its location relative to the beginning of the track segment. After movement of the head to another data zone and after power to the servo electronics is restored on recovery from a power saving mode, the correct data sector for reading or writing is located by use of the number of the data sector following the first servo sector read by the head. This avoids the latency penalty that would occur if the disk drive had to wait until the next beginning-of-track index mark.
