ABSTRACT:
Information signal reproducing apparatus operates to recover an information signal from record tracks at normal and fast-speed playback modes. Dropouts in the information signal reproduced from the tracks are detected to commence a correction signal interval which ends when a synchronizing signal in the reproduced information signal is detected. A corrected information signal is produced by substituting a correction signal for the reproduced information signal substantially throughout the correction signal interval when the apparatus operates in a fast-speed playback mode.
