Claims
- 1. An optical disk recording method of recording data on an optical disk by applying laser light to a track of said optical disk, comprising the steps of:a) applying a light flux to the track in sequence in such a manner that the light flux crosses said track obliquely with respect to a plurality of rows of record marks; and b) producing the plurality of rows of record marks in said track.
- 2. An optical disk drive for reproducing data recorded in a track of an optical disk on which a plurality of rows of record marks are formed in one track, by applying laser light to the track, comprising the steps of:a) applying a reading light flux to the track in sequence for the plurality of rows of record marks in such a manner that the light flux crosses said track obliquely with respect to the plurality of rows of record marks; and b) causing reflected light to be generated from the plurality of rows of record marks by the incident light flux successively, mixing the reflected light, and reproducing a signal changing according to states of said plurality of rows of record marks; and c) demodulating the data recorded in the track from the reproduced signal according to a predetermined decoding algorithm.
