PURPOSE:To set easily an initial position with a manual operation in a reproducing mode, by displaying the initial position at the position corresponding to a prescribed position of each information group recorded on a surface opposite to a signal recording surface of a recording disk which has the signal recording surface only on its one side. CONSTITUTION:Plural information groups are recorded on a signal recording surface 1a. At the same time initial position displays 2a, 2b, 2c and 2d are applied concentrically to a center hole 3 of a signal recording disk 1 at positions corresponding to the initial positions of each information group on an opposite surface 1b by printing the head position of each recording information group. A signal detecting part such as an optical pickup, etc. is positioned at the displays 2a-2d respectively. As a result, the program searching is simply possible for the desired music. |
