Abstract
An information recording/reproducing apparatus which is capable of recording information data even if prepits cannot be correctly read from a recording medium. Prepits are detected from a read signal retrieved from a recording medium to generate a prepit detection signal, and a block signal indicative of a recording timing is generated based on the prepit detection signal. In this event, when the prepit detection signal is normal, an information signal is recorded on the recording medium at a recording timing in accordance with the block signal. On the other hand, when the prepit detection signal is defective, the information signal is recorded on the recording medium at a recording timing in accordance with an auxiliary block signal having the same period as a block length, and a fixed phase.
