PURPOSE:To shorten remarkably a access time to a data signal and to prevent a damage caused by other signal by placing the data signal between a start signal and an information signal. CONSTITUTION:After t1 has elapsed from a time point of T0, a start ID signal for obtaining a timing for reading an information signal is continued for t2, and after a blank of t3, a data signal is continued for t9. Thereafter, after a blank of t11, an information signal is started. During the first t4, it is a common part to the previous sector, a portion of the remaining t5 is a new information signal, and this time is a variable length. After a blank of t6, an end ID signal is continued for t7. Next, after a blank of t10, it is continued to the next sector. According to such a signal array, when reproducing it, the access time to a data signal which is stored in a memory 11 is shortened extremely, therefore, based on this data signal, the information signal can be reproduced in an extremely good state.
