Abstract
A partitioning format for magnetic tape media that includes at least a first portion (e.g., a file directory) having a plurality of dynamically updateable (e.g., non-shingled) partitions and a second portion (e.g., a data portion) having a plurality of linearly or sequentially written shingled partitions. Use of both shingled and non-shingled partitions on the same length of magnetic tape allows for an increase in capacity over those applications that perform linear recording of non-shingled partitions while allowing for the dynamic updating of a local file directory free of disturbing the linearly written data of the shingled partitions.
