Abstract:
A method for extracting data from a device storing data in a first format, wherein the first format is comprised of a plurality of tracks, wherein each track has at least one data area, and wherein each data area is comprised of at least one addressable block of data, comprising the steps of:(a) receiving a request from a host system for an address of a block of data in a second data format;(b) determining a byte displacement value for the requested address;(c) locating a data area in a track in the device having a byte displacement value less than the byte displacement value for the requested address;(d) determining a byte location offset by subtracting the byte displacement value for the located data area from the byte displacement value for the requested address;(e) determining a location in the located data area of a block of data at the byte location offset; and(f) providing the host system with the located block of data.
