Abstract:
An optical disk recording apparatus for recording first standard information and second information on a disk-like recording medium by a laser beam, comprising:modulation signal generating means for generating a modulation signal which changes in response to said first standard information;time change signal generating means for generating a time change signal which changes in accordance with said second information;light amount changing means for changing a light amount of said laser beam in accordance with said time change signal; andoptical modulating means for modulating a laser beam by turning on and off said laser beam, whose light amount is changed by said light amount changing means, in accordance with said modulation signal generating means, wherein said laser beam modulated in accordance with said optical modulating means irradiates said disk-like recording medium to thereby record said first and second informations on said disk-like recording medium within a common pit train.
