摘要： A magnetic drum has a plurality of record-reproduce heads along its surface. A common shaft having pins at precisely spaced intervals serves both to hold the heads in registration and to lift them from the surface of the drum. The device is journaled in bearings which serve as doweling to position split-end plates of the drum housing assembly. The drum is removable to permit interchangeability.
