ABSTRACT:
The present invention is a random accessible signal filing system containing magnetic discs, at least two buffer memories and a circuit for controlling the buffer memories in such a way that the write-in and read-out of at least two of the buffer memories may be alternately performed, whereby through random access, the required signals are selected and read out so as to be outputted as a series of signals.
In this system, during the outputting of the signals, the signals coming from the magnetic discs are written into one of the buffer memories sector by sector at the read-out speed of the magnetic discs, and thereafter, are read out at the demodulating speed of the demodulator. The two buffer memories are so controlled that while the signals are written into one of them; the signals are read out from the other.
