Abstract
A data record formatting system for an optical recording medium in which the reading and/or writing is carried out along tracking lines, and a data reading/writing system for the optical recording medium of the type is disclosed. The data record formatting system for the optical recording medium comprises tracking portions used as a reference for the reading and/or writing operation and data recording portions for storing data. The tracking portion and the data recording portions are alternately arranged along the same line in a data recording region of the optical recording medium. The data reading/writing system for the optical recording medium comprises a track-tracing detecting arrangement for setting a light spot or spots on the optical recording medium to trace the tracking portions and a reading/writing arrangement for setting a light spot on the optical recording medium to read and/or write the data. The track-tracing detecting arrangement and the reading/writing arrangement are arranged so that the light spots set on the optical recording medium are disposed on and along the line in which the tracking portions and the data recording portions are alternately arranged.
