The invention provides a tape drive comprising a head mounted on a
turntable. The turntable rotates to allow the head to access first and
second sides of a data storage tape. Techniques for accessing the first
and second sides may include rotating the turntable to position the head
in first and second positions. In addition, the techniques may further
include raising and lowering the turntable relative to the data storage
tape in order to facilitate access to both sides of the data storage tape
without requiring the data storage tape to be unspooled and re-spooled.
