Abstract
The address of each track in a disk drive system is expressed in Gray code, and an appended bit of information is added to the Gray code, associated with the least significant bits thereof, the value of which is determined by the values of the most significant bits of the Gray code. The value of this appended bit is the same from Gray code to successive Gray code, as long as there are no changes in any significant bit between successive Gray codes, but the appended bit changes value when there is a change in a most significant bit between successive Gray codes.
