Title: Pulse code modulation recording and reproducing apparatus

Abstract: A PCM recording and reproducing apparatus comprising an error detecting circuit for detecting a frame including at least one word information signal with an error, the frame being a reproduction signal read from a recording medium on which certain pulse coded information is recorded in a frame distribution system, and a compensating circuit for compensating the reproduced information signal by the use of the output signal from the error detecting circuit, thereby removing the adverse effects of information dropout in spite of a high density recording.
