Abstract

A data storage drive arranged as a plurality of logical accessors accesses data on a removable random access medium. Upon a write access for a data segment by a logical accessor, a control locks a context comprising at least one data segment of a partition to the logical accessor. The control concurrently allows read access to the data of the removable random access medium, except the locked context, and allows write access, except to the locked partition, by other logical accessors.
