Abstract: Read positioning method includes adjusting at least one read head position when accessing read track on at least one rotating disk surface based upon Burst Correction Value of nearest write track, when PES burst patterns of read track and nearest write track match. Apparatus supporting read positioning method may include means for at least partly performing each step. At least one means may include at least one instance of at least one of following: computer, finite state machine, neural network and inferential engine. At least one read method for the hard disk drive included. These read methods may be used during initialization and/or normal hard disk drive operation. Hard disk drive may include servo controller driving voice coil actuator and, preferably further driving micro-actuator. The hard disk drive may include more than one rotating disk surface and more than one rotating disk surface.

Abstract: A method of mapping logical track numbers to a collection of physical tracks on at least two disk surfaces within a disk drive. The method further includes accessing logical tracks at assigned physical tracks. The invention includes making disk drives using the mapping of logical tracks to physical tracks and those disk drives as a product of that manufacturing process. The invention also includes program systems implementing the mapping of logical tracks to physical tracks within the disk drive and disk drives implementing the method of assigning logical tracks to physical tracks and/or accessing logical tracks based upon the physical track assignment.
