A record confirmation apparatus comprises a recording device for recording information on a disc-like record bearing member rotated at a predetermined angular speed, in accordance with a writing signal, a reproducing device disposed at a predetermined distance from the recording device in the tangential direction of the record bearing member for reproducing the recorded information as a read-out signal, and a comparing device for delaying the writing signal and comparing it with the read-out signal, the comparing device having a variable delay circuit for varying the delay time in conformity with the relative position of the recording device and the reproducing device relative to the record bearing member in the radial direction of the record bearing member.
