More Information
Summary:An optical information recording and reproducing apparatus comprises, an optical head for recording and reproducing information on and from a card-shaped optical recording medium, first means for relatively reciprocally moving said optical head to said card-shaped optical recording medium, and control means for controlling a relative speed between said optical head and said optical recording medium, said control means keeping a constant relative speed between said optical head and said optical recording medium in a record area of said optical recording medium and changing the relative speed between said optical head and said optical recording medium and reversing the direction of the relative movement between said optical head and said optical recording medium in areas outside of the record area.
