Abstract

PURPOSE: To increase the recording density, by detecting the conditional change of a plurality of signals to be recorded, changing the renewing speed of the memory address with the condition, and performing the career recording in minimum area.
CONSTITUTION: The signal change detecting circuit 12 outputs the signal 16, when someone of the input signals A, B, C among the signals A...G to be traced changes from "0" to "1" or "1" to "0". This signal 16 starts the counter 13, sets FF14, and FF14 is reset with the signal changed of small one of the inputs A, B, C after a given time On the other hand, the inputs A...G are stored in the register 11, the output is used for write-in of the memory 10, and the memory 10 is determined with the output of the address counter 15. In this case, the counter 15 feeds the sampling pulse Sα or Sβ in period α or β based on the condition of FF14 to the memory 10, renewing speed of the memory adress is changed to perform career recording in the minimum area and the recording density can be increased.
