Head transfer apparatus, head transfer method, and reproducing apparatus

摘要

A present invention relates to the clearing of an obstacle if smooth transfer of a head is interfered with in an apparatus for reproducing data recorded in a recording medium having address information. If an obstacle is detected, the head frictionally engaged in a movable manner with a drive shaft secured to an oscillation actuator that expands and contracts in response to the application of a drive signal is transferred by driving the oscillation actuator such that it expands and contracts at different speeds.
