sector

The unit in which data is physically stored and protected against errors on a fixed block architecture disk.

A sector typically consists of a synchronization pattern, a header field containing the block's address, data, a checksum or error correcting code, and a trailer. Adjacent sectors are often separated by information used to assist in track centering. Most often, each sector holds a block of data. See disk block.
