sector interleave
(Or sector map) The mapping from logical to physical sector numbers on a magnetic disk designed to optimise sequential reads and wr ITes. Data is usually transferred to and from the disk in blocks or sectors where one sector lies w IThin a continuous range of rotational angle of the disk. If logical sectors are assigned sequentially to physical sectors (0,1,2,...) then by the time one sector has been read and processed (e.g. wr ITen to main memory) the start of the next logical sector will have passed the read/wr ITe head and will not be accessible until the disk' s rotation brings IT back under the head. Staggering the physical sectors (e.g. 0,3,6,1,4,7,2,5,8) aims to allow just enough time deal w ITh one sector before the next is accessible. This obviously depends on the relative speed of the rotation of the disk, sector size, sectors per track and the speed of transfer of sectors to main memory.
