摘要：
A recording disk carrying a compressed video signal at a high recording density and a recorded information reproducing apparatus for reproducing the information recorded on the particular recording disk. A linear velocity of the reading of information is adjusted according to a data quantity signal reproduced from the recording disk having data areas in which a compressed video signal produced by the compression and coding process is recorded in predetermined unit blocks (GOP block) and at least a data quantity information recording area in which a data quantity signal representing the quantity of each unit of the compressed video signal is recorded.
