Abstract
In an information recording/reproducing apparatus in which recording of information is effected by scanning an information track of an information recording medium with a recording light spot an verification is effected simultaneously with recording by scanning with a verifying light spot, there are provided a memory for storing the recording data released from the memory, and a second resister for temporarily storing reproduction data obtained for verification. The data transfer is performed in such a manner that the recording data from the memory are held in succession by a predetermined unit of data in the first register and the reproduction data are held in succession by predetermined unit of data in the second register.
