A position transducer capable of accurately detecting an n-bit code by a small number of ABS detectors when there is provided one ABS track. In an ABS head, the ABS detectors 101 to 10n+m are disposed for a distance lambda 1 between the first ABS detector 101 and (n+m)th ABS detector 10n+m to satisfy a requirement (n-1) lambda + 2 delta < lambda 1 and a distance lambda 2 between two successive ones of the ABS detectors to satisfy a requirement 2 delta < lambda 2 < lambda - 2 delta , so that at least one ABS detector is opposite to a stable area T in each of micro-areas at n successive bits. <IMAGE>
