Abstract

PURPOSE:To effect the record of an excellent S/N ratio by operating a plurality of heads, which are arranged along the same track, each delay time thereby to effect the multiplex recording operations. CONSTITUTION:One of the input signals fed to the heads 3 and 8, which are arranged on the same track, is impressed upon the head 8 by way of a delay circuit 6 of a delay time corresponding to the time period, for which a magnetic recording medium 1 accomplishes one turn, so that the same input signals are recorded in a multiplex manner through the head 8 in the position of the medium 1 which has been recorded with the input signals by the head 3. By the multiplex recording operations having no positional shift with the use of the plural heads, the signals having no repetition can also be recorded in a satisfactory S/N ratio.
