Method of implementing a geometry per wedge (GPW) based headerless solution in a disk drive formatter and a computer program product incorporating the same
A method of implementing a geometry per wedge (GPW) based headerless solution in a disk drive formatter having a corresponding memory buffer. The disk drive formatter includes high and low processing engines and formats a data storage disk. The method includes the step of processing a command instruction, which instructs the high-level processing engine to execute a disk operation with respect to a predetermined sector. The method also includes the steps of searching for the predetermined sector using sector layout information derived from a GPW table including entries which define the relative position of sector pulses on a track within a data wedge of the disk, and transferring the predetermined sector from the disk to the buffer memory.
