Abstract

PURPOSE:To equalize the frequency characteristic of an information signal recording current over all recording positions of a recording medium and to suppress the erroneous reproduction at the time of reproduction, by changing the frequency characteristic of a recording current due to the difference of the recording track position of the recording medium of an information signal recorder. CONSTITUTION:When a recording mode is set by a control circuit to control the whole of a recorder, switches S1 and S2 are connected to an (a) side (reproduction) and a recording amplifier 1 is connected to first and second step-up transformers 5-1 and 5-2. A still picture signal inputted to an FM modulator 7 is frequency-deviated and a carrier is directly FM-modulated. When a recording starting command from a control circuit is the frame recording, during the rotational period of a magnetic sheet 4, a first field signal is supplied to a first magnetic head 2-1 and a second field signal is supplied to a second head 2-2 by the next one rotation. A magnetic head position detector 11 detects that the head 2-1 becomes a prescribed position, the head is inputted to the amplifier 1 and due to the difference in the recording track position, the frequency characteristic of a recording current is changed.
