Abstract:
1. A head transfer apparatus for controllably transferring a head, for reading data from a recording medium in which address information indicating a recording position has been recorded, to a vicinity of an input target address, the head transfer apparatus comprising: drive shaft means frictionally engaged in a movable manner with the head; oscillation actuator means having one axial end thereof that expands and contracts upon application of a voltage and being secured to a fixing portion, an other end of the oscillation actuation means being secured to the drive shaft means; driving means for transferring the head in a predetermined direction by supplying a signal for setting the expansion and contraction of the oscillation actuator means at different speeds to the oscillation actuator means; and controlling means for carrying out control such that the oscillation actuator means is driven by the driving means to cause the head to move alternately in one direction and in an other direction for a predetermined time when it is determined that a transfer of the head is being interfered with.
