A rotary head type reproducing apparatus wherein, three rotary heads are arranged to be capable of simultaneously tracing different parts of many parallel tracks formed on a record bearing medium, the parts differing from each other both in the transverse and longitudinal directions of the tracks; among the three heads, a first head is positioned in the middle part of each track in the direction of the width thereof; a first tracking error signal is formed to represent a level difference between pilot signals reproduced by the first head from second and third tracks adjoining both sides of a first track which is being traced by the first head; a second tracking error signal is formed to represent a level difference between pilot signals reproduced from the second and third tracks by second and third heads which are other than the first head; and tracking control is accomplished by using both the first and second tracking error signals.
An apparatus for reproducing information with rotary heads from a record bearing medium on which an information signal and pilot signals are recorded in many parallel recording tracks, comprising:
