Title: Method for correcting added and lost bits in a hard disk drive using error correction codes

Abstract: A hard disk drive with an encoder that writes data onto a disk in accordance with a plurality of first codes. Each code contains a plurality of digital bits. The first codes are selected so that if a bit is added or dropped during a write or read process the resulting bitstream can only be one of the selected first codes. This allows the bitstream to be accurately decoded to detect and correct for the added/dropped bit.
