Abstract
PURPOSE: To realize a picture recording and reproducing system of simple constitution which provides direct recording on and reproducing from a magnetic recording medium by binary-coding input information on patterns and characteristics.
CONSTITUTION: Picture information input device 2 scans picture information to output double-gradation signal S1 of white and black levels. Binary pulse converter circuit 3 converts signal S1 into a binary signal, which is recorded on magnetic recording medium 8 through write amplifier 5. Signals read out through head 7 and reproducing amplifier 9 are in a differential waveform of a write binary signal and this signal is adjusted in amplitude by emphasis circuit 10 nearly to a constant value and then displayed on display unit 13 by way of amplitude discriminator circuit 11 and binary pulse generating circuit 12.
