Abstract

PURPOSE: To record information on both recesses and projecting parts and to allow the reproduction of stable address signals without having crosstalks by recording the address signals respectively to the recesses and projecting parts of the guide tracks of a disk in such a manner that said signals are not adjacent to each other.
CONSTITUTION: A region 29 on the diagonal line of an address region 3 on the disk 1 indicates another address region. The region 29 is formed of rugged shapes in the tracks 8 for tracking control, unlike the region 3 which is formed of the rugged shapes in the information tracks 8. The address signals are recorded to both of the recesses 7 and projecting parts 8 of the guide tracks in such a manner and both the address signals are so disposed as not to be adjacent to each other and, therefore, the stable address signals having no crosstalks can be reproduced even in case of recording and reproducing the information to and from both of the recesses and projecting parts. The prescribed track can be exactly found out at the time of accessing or off tracking.
