ABSTRACT:
The present invention provides an AD converter which operates at high speed with low power consumption and a magnetic recording/regenerating apparatus using the same. The magnetic recording/regenerating apparatus has a current controller for switching the operating current of the comparator of the AD converter and an ADC controller for receiving an instruction of the conversion speed corresponding to the regenerating frequency. When the current controller receives an instruction for decreasing the conversion speed, it puts an operation state of the AD converter into a low power consumption state.
