Title: Frequency encoding method of recording binary signals on tape - employs standard tape and cheap cassette recorders so that only one signal state is encoded by frequency modulation
Inventor: WICHODIL KARLHEINZ
IPC: G11B20/10
Filed: 1979-06-12
Abstract: Using standard tape and low priced cassette recorders for recording binary signals employing a frequency encoding method complex read/write circuits are normally required and this results in low read/write speed. This is overcome by making the system self clocking and by employing only two frequencies, 4,8 and 6,4 Hz, both being a multiple of the clock frequency of 800 Hz, the usual third frequency for zero being superfluous. A phase locked loop (PLL) circuit (H1) demodulates the recorded signal derived from the recorder (N1), a potentiometer (P1) determining the frequency of the PLL circuit. The demodulated signal passes through a differential amplifier (Y1) to the output terminal (DA). PLL H1 is followed by another PLL circuit (H2) tuned to 800 Hz which via a divider becomes the read strobe signal. 6.4 kHz corresponds to "high" and 4.8 kHz to 'low'.
