Abstract
A magnetic drum/head system for selectively reproducing voice information recorded on the magnetic drum. The magnetic drum has a recording zone in which predetermined voice information is recorded in each track thereof and a non-recording zone between a starting end of the recording zone and a terminating end of the same. In case of a track selection, the magnetic drum is held still so that the non-recording zone is in a confronting relation to the magnetic head, and the magnetic head is driven to move along the non-recording zone to the selected track. The magnetic drum is then rotated to reproduce the selected voice information.
