Abstract
An information recording apparatus has a write canceling circuit that monitors interface signals fed from a host and that, when the interface signals are recognized to be abnormal, inhibits write operation against a recording medium either for a predetermined period or until a predetermined condition is fulfilled. This circuit configuration helps eliminate or reduce the occurrence of erroneous write operation as occurs when the received interface signals are abnormal.
