ABSTRACT:
A rotating head type reproducing apparatus for reproducing an information signal with rotary heads from each of many recording tracks formed in parallel with each other on a tape-shaped record bearing medium including a cylinder member arranged to have the tape-shaped record bearing medium wound around the cylinder member at a wrap angle which is at least ##EQU1## wherein "n" represents an integer at least 3, a number "n" of rotary heads arranged to revolve around the periphery of the cylinder member at a phase difference of 360.degree.
from each other, an arrangement for reproducing the information signal by selectively using one by one signals reproduced respectively by the "n" number of rotary heads; and an arrangement for controlling the positions of the "n" number of rotary heads relative to the record bearing medium by using at least one of signals reproduced by an (n-1) number of rotary heads other than one of the "n" number of rotary heads which is in use by the reproducing arrangement.
