Abstract
PURPOSE: To reduce the dot spacing in a recorder of multi-stylus system thereby to make the waveform data readable by interpolating the similar interpolating data between recording dots.
CONSTITUTION: An analog waveform signal is converted by an A/D converter 1 into the waveform data having digital codes, which are then fed to a data processing circuit 2. If waveform data such as A to D are given, a function indicating a straight line L1 jointing the two points A and B is first calculated. Then, the value of the linear functions is calculated for each dot timing and is inserted as the interpolating data between the two points A and B so that the records E1, E2 and so on are attained. Like processes are accomplished between the points B and C and the points C and D. Thus, the records which have a narrow recording dot spacing and which have a readable waveform can be obtained for each waveform data applied.
