Abstract
A control circuit is used for matrix drive recording. It includes a microprocessor, a RAM for storing data to be recorded therein, an address signal editing circuit for modifying the input addresses to the RAM, a shift register for converting the data from parallel to serial form and transferring it to a recording circuit, and a DMA controller for reading the data from the RAM and transferring it to the shift register.
