Abstract

Disclosed is a headerless hard drive system that includes a head-disk assembly, a servo control logic, and a format calculator. The head-disk assembly includes a set of recordable disks for storing data. Each recordable disk having a plurality of tracks with each track having a plurality of servo wedges for dividing the track into a plurality of data frames. In this arrangement, one data frame is associated with one servo wedge and the tracks do not contain any header information that uniquely identifies the data frames in the tracks. The servo control logic coupled to the head-disk assembly to process the servo wedges for generating a signal that identifies a servo wedge being processed on a track. The format calculator is configured to convert the signal that identifies the servo wedge being processed to an associated sector number on the track. In addition, the format calculator is adapted to compute a set of parameters including ending and beginning split sector sizes and the number of whole sectors in the data frame associated with the servo wedge being processed.
