ABSTRACT:
A storage media for linear, serpentine recording is pre-formatted for data storage operations by recording partition format information in a single pass along the length of the storage media by recording partition format information for all storage media tracks at regular partition intervals defined by index locations alternately in both storage media directions before moving the storage media to the next partition interval. At each index location, partition markers are recorded in successive parallel tracks first in one media direction and then the other until markers are recorded across the entire width of the storage media. The steps of moving to a next partition index location, recording partition information in successive parallel tracks in first one direction and then the other, and moving to a next index location one partition length away, are repeated until all partitions of the storage media are pre-formatted.
