摘要 |
An optical recording medium that enables a recording or reproduction apparatus to perform accurate tracking servo control even if intersymbol interference occurs. An optical recording medium includes a plurality of frames continuously extending in an information reading direction. Each frame is defined by a servo region for recording tracking pits used in tracking servo control and a data region for recording information data. A position of each of the respective tracking pits in each respective servo region is changed in the information reading direction between successive frames.
