Abstract
A PCM record reproducer comprises a coder circuit for forming PCM signals by adding error detection codes to data signals in a predetermined pattern; a splice detection circuit for determining a splice point of a magnetic tape by finding inconsistency of the detected result of said error detection code depending upon said PCM signals read-out from said magnetic tape in which said PCM signals are recorded; and an editing circuit for editing said PCM signals when the splice point is determined by said splice detector circuit.
