sector interleave

Definitions

Computing

  • noun the ratio of sectors skipped between access operations on a hard disk; in a hard disk with an interleave of 3, the first sector is read, then three sectors are skipped and the next sector is read; this is used to allow hard disks with slow access time to store more data on the disk

Electronics

  • On a magnetic or optical disk, to position sectors (2) in a manner which improves performance. For example, if a data file spans more than one sector on a hard disk, these sectors may be staggered so that all sectors can be read in a single revolution, as opposed to multiple turns. This speeds up access time. Also called sector map (1).
