ABSTRACT:
In one embodiment, first and second levers of a tape head actuator are balanced using first and second masses carried on first and second sides, respectively, of the first and second levers. The first and second levers are linked with a link member of the first mass which further includes a tape read/write head supported by the link member. In the illustrated embodiment, the levers are linked by the pivotally connected link members to form a four member linkage. The tape read/write head may be carried by the link member. Other embodiments are described and claimed.
