(under subclass 275.1) Subject matter wherein a recurrent or repeated data arrangement, pattern, sectors, or data blocks occur on the information medium.
(1) Note. An organized pattern interrelates with an information arrangement pattern.
(2) Note. Examples are: Pre-formatted subject matter wherein data or certain track structure (e.g., guide grooves, etc.) has been pre-recorded, pre-etched or pre-formatted on the storage medium, having servo, index or address sectors or segments or tracks set forth as to there location with respect to other data on the storage medium; radial dependent parameter on disc medium subject matter wherein the data or information on a disc type storage medium has some parameter of the signal or track structure which varies as a function of the disc radius (e.g., pit size in some dimension varies
dependent as a function of disc radius, or CLV/constant linear velocity format of recorded data, etc.).

44.26, for servo system operation related to disc structure information format.
94, and 95, for systems using a storage medium element with more than one plane of distinct tracks of recording information.
111, for systems using a spiral or helical track. 280, where the disc thickness varies as a function of the radius.
