DOT RECORDING HEAD TYPE ANALOG WAVEFORM RECORDING DEVICE

PURPOSE:To record an analog waveform almost on real-time basis to high density without increasing its memory capacity by superposing and writing a dot pattern signal of a unit recording surface stored in a buffer memory on the contents of an output memory with the capacity of one unit recording surface. CONSTITUTION:The writing, reading, erasing, etc., of the output memory 30 with the capacity corresponding to one unit recording surface are controlled by a write control circuit 40, output signal control circuit 50, etc. Then, a dot pattern of a unit recording surface stored in the buffer memory 21 of a dot pattern signal generating part 20 is written on the memory 30 while superposed and shifted longitudinally by one dot line, read out while shifted longitudinally by one dot line, and supplied to a dot recording head 12 to record the analog waveform almost on real-time basis to high density without increasing the memory capacity.
