Abstract
A signal recording and reproduction system is used in recording and reproducing signals on and from a recording medium such as a compact disk, laser disk, video disk or digital audio tape. Index data for the recorded contents such as Table of Contents data (TOC) or the like, are stored in the recording medium. The signal recording and reproduction system confirms the time necessary for playing or reproducing a desired reproduction range of record sections in the recording medium, using a small number of steps of operation.
