Patent ID: 6870802

Claim:
An information reproduction apparatus comprising: a rotating section for rotating a disk-like information carrier on which a plurality of pieces of continuous information each capable of being continuously read out are recorded; a CLV control section for controlling the rotating section in such a manner that the information carrier is rotated at a constant linear velocity; a CAV control section for controlling the rotating section in such a manner that the information carrier is rotated at a constant angular velocity; a rotation control selection section for selectively operating the CLV control section or the CAV control section; and an information determination section for detecting an information length of each of the plurality of pieces of continuous information, wherein the rotation control selection section is constructed in such a manner as to selectively operate the CLV control section or the CAV control section for a respective one of the plurality of pieces of continuous information based on the detected information length of the respective one of the plurality of pieces of continuous information by the information determination section.
