Abstract
PURPOSE: To make it possible to correct drop-out of digital data by recording signals, which are not subjected to A/D conversion, on a track other than the track where signals subjected to A/D conversion are recorded, and subjecting them to A/D conversion after reproducing to correct code errors.
CONSTITUTION: Analogue signals become digital signals by sample hold and A/D converter 2 and are recorded on a magnetic tape. Simultaneously, analogue signals which correspond to the (n+1)th bit of these digital signals and are not subjected to A/D conversion are recorded on a track other than the track where digital signals are recorded. When these recordings are reproduced and analogue signals are converted to digital signals by A/D converter 15 and are added to reproducing digital signals applied to digital multiplexer 17, minimum data of unrecoverable digital reproducing signals of much data drop-out is secured, and reproducing signals where pulsatile noise is reduced are obtained.
