Abstract
A performance optimized computer data recording media format and associated control logic method is disclosed. Localized data block recording, such as by concurrent parallel or serpentine recording techniques, is used to create a series of Virtual Volumes on a single physical volume. Physical localization of data blocks records is achieved which tends to minimize access time. Using the Virtual Volume construct, other industry standard data storage systems can be emulated. Many data storage operations requesting physical motion are translated into virtual motion which in turn results in significantly less physical motion than that requested, thereby reducing access times and media and drive apparatus wear.
