ABSTRACT An optical disk recording and reproducing device capable of recording and reproducing data to or from an optical disk. Continuous signals representing continuous analog information such as audio and video information and discrete signals representing discrete data-information such as numerical data including program codes or character data are recorded dividedly in different recording regions provided on an optical disk. including erasable or write once type disks. The optical disk is rotated at a given linear or rotary angular speed under control by a disk rotation control device so as to simplify rotational control of the optical disk in accessing the information in the divided regions.
