PURPOSE:To prevent assuredly the generation of a reproduction error despite a variable speed reproduction mode, by providing a signal converter which performs the partial response equalization only to a recording circuit. CONSTITUTION:A digital signal Sa is converted into another digital signal Sd and also supplied to a signal converter 30 which performs partial response equalization. A partial response equalized ternary equalized signal Sg is delivered from the converter 30 and recorded on a tape 31. Then the reproduced signal Sg is reproduced to a digital signal via a preamplifier 16, etc. The converter 30 is provided only to a recording circuit 10A, and therefore the signal Sa can be always reproduced assuredly regardless of the tape speed. This can prevent assuredly the generation of a reproduction error despite a variable speed reproduction mode. |
