摘要

Each data storage disk, preferably with a single spiral track, has an addressable track that is independent of the length of the disk or spiral track rotation. Each rotation can include non-integer castable tracks and sectors. An optical disc is used to describe the present invention. The circumferential position of the track and the sector advances circumferentially. Each of the plurality of radially arranged rotating bands has a fixed number of rotations and each of the radially arranged rotating bands has a fixed number of rotations and a radially larger number of addressable tracks in the outer band . The number of bands is 2ⁿ Where n is an integer. Each band is divided into a plurality of rotation groups each having a fixed number of rotations. Each group in the band has the same number of addressable tracks. The so-called fixed sector has one end fixed to the reference circumference position on the disk. Each rotation group starts at a fixed sector, and all other sectors in the group are positioned circumferentially with respect to the fixed sector. Addressable track searching of discs, other embodiments and disc manufacturing processes have been described.
