Abstract: The present invention comprises an implementation of a variable data TPI hard drive system. In one embodiment, the system is implemented by configuring a group of servo tracks in a radial direction for a hard drive media. The group is comprised of an integral number of servo tracks that is constant throughout the drive device. The number of data tracks in a group is also an integer but will vary for each surface according to the head used for R/W operations for each media surface. Group boundaries coincide with media surface R/W zone boundaries. The groups are accessed in hard drives having multiple surfaces in a serpentine manner. Data tracks per group are reduced from what is achievable to produce desired target capacities.

Abstract: A system for implementing substantially all vendor unique commands in a host computer instead of an electronic storage device. Alternative vendor unique commands are provided to implement a remote procedure call (RPC) protocol to implement vendor unique commands resident in the host computer with functions in the storage device. The storage device functions are substantially only the functions needed for normal, non vendor unique electronic storage device (ESD) operation. To facilitate access from the host computer to ESD functions, data, and constants, a symbol table of the storage device's software is used. The resulting system provides for a smaller code footprint in the storage device and easier to maintain and enhance function in the host computer.
