ABSTRACT:
In an optical disk drive apparatus for recording data on and reproducing data from an optical disk using both of data recording tracks formed of grooves and lands, is divided into an integer number of sectors, and the address data area of each sector is shifted in the radial direction. When a first sector is scanned, a data from the address data area of the first sector is read as a first direct address data, and a data from the address data area of an adjacent sector is read as a second direct address data. A first modified address data of the first sector is produced by modifying the second direct address data with an inter-track address difference, and a correct address value of the first, sector is produced using the first direct address data and the first modified address data.
