An information recording and reproduction apparatus has a recording-use memory and a reproduction-use memory. The reading speeds of the respective memories are set so as to be equal to the reading speed derived from the carrier central frequency of the absolute address which is pre- recorded on a disk based on the constant linear velocity control method. With the arrangement, the simultaneous recording and reproduction of information with respect to different portions on the disk is carried out at a high speed without changing the rotation speed of the disk.
