Claim One:
1. A method for retrieving one or more blocks of data from a tape media, the method comprising: receiving a request to retrieve multiple groups of at least one block of data; retrieving a device block map from a tape media indicating positions of the groups of at least one block of data on the tape media and storing said device block map in a memory location; generating from the device block map in memory an image of a physical layout of the requested groups of at least one block of data on the tape media; determining an optimal order to retrieve the requested groups of data based on the physical layout of the requested groups indicated in the image in a manner that minimizes an operational time of retrieving the requested groups of at least one block of data; and retrieving the requested groups of at least one block of data from the tape media using the determined optimal order.
