Abstract

PURPOSE:To shorten the time required for program searching of a tape in reproduction by using a solid memory unit available for random reading of a recording medium and for conversion from an analog signal to a digital signal. CONSTITUTION:Recorded information, outputted from data collecting output unit 16 as a bit-by-bit parallel signal, is converted by P/S converter 17 into a series signal and this bit-by-bit series signal is demodulated by demodulator 18 from the digital signal to an analog electric signal waveform. After its high frequency noise is removed by LPF19, it is converted into a sound at speaker 21 by way of output amplifier 20. In this case, unit 16 can fetch digital data from solid memory unit to any address at random and then take the contents of the memory out at random, so that the time required for program searchig in reproduction can be shortened. The memory capacity, however, is limited, so that using this for announcement at a station will result in large effect.
