ABSTRACT:
Disclosed is a head shifting apparatus for shifting a head relative to a recording medium, which comprises a shifting mechanism for shifting the head stepwise, detecting means for detecting when the head reaches a predetermined reference position and control means for controlling the shifting mechanism in such a manner that the head is shifted in a first shifting mode where the head is shifted on the basis of a predetermined first unit increment of shifting step until the head reaches the reference position, and after that when to perform normal recording or reproducing, the head is shifted in a second shifting mode where the basis is shifted on the basis of a predetermined second unit increment of shifting step larger than the first unit increment of shifting step.
