Title: Magnetic recording system
Inventor: MATSUMOTO TAKASHI
IPC: G11B20/02
Filed: 1987-04-17
Abstract: PURPOSE:To realize the satisfactory reproduction even with a narrow guard band by applying the FM modulation to a sound information signal or another information signal by means of a carrier wave of 2.5-5.5MHz and at the same time recording magnetically said information signal to a metal coated floppy disk. CONSTITUTION:A still picture sent from an electronic still camera main body, for example, is recorded on a main track of a metal coated floppy disk 19 in the form of the FM modulated picture signals. In this case, the FM signals showing the still picture have the + or -1.5MHz deviation with a center frequency of 6MHz. When a sound recording switch 13 is turned on, the sound signals supplied from a microphone 1 are supplied to a time base compressor 6 and the FM signals undergone the time compression synchronously with the PG signal received from a PG detector 14 are recorded on a guard band formed between adjacent main tracks. In such a case, the signal processed by an FM modulator 16 has the + or -1.5MHz deviation with a center frequency of 4MHz.
