Abstract

PURPOSE:To secure the reproduction in various types of modes including the still picture mode, the slow motion mode and others when the information of the information record medium disk is reproduced by realizing a high-speed transfer of the reproduction element in the diameter direction of the disk and giving the random access to the information recorded on the disk. CONSTITUTION:The bits corresponding to the signals are arrayed spirally on the flat surface so that the picture information signals of the N vertical scanning period may exist every section corresponding to one turn of the information record disk. And then the spiral record tracks caused by the signals are recorded on the flat plane with the fixed record track spaces, and the disk is turned with the fixed rotary cycle, Furthermore, the reproduction element is transferred in the diameter direction and with the necessary shifting velocity according to various type of reproduction modes so that the reproduction element may follow accurately the record tracks of each reproduction under the tracking control and in accordance with each reproduction mode. Then the signals are read out via the reproduction elements in order to secure alteration for the reproduction mode into the modes of the still picture and the slow motion picture.
