Abstract
A magnetic head assembly in a linear tape system having an interface region having a substantially flat region with a substantially square leading edge and at least one cavity in the flat region. The cavity has a depth of about 0.5 micrometers to about 20 micrometers. At least one read-write element is located on the flat region adjacent to the cavity. As a magnetic tape traversing the interface region, a sub-ambient condition is generated. The magnetic tape is bent or otherwise deformed as it passes over the cavity, thereby increase tape stability at the interface with the read-write elements. A magnetic tape system for recording, reproducing and/or erasing magnetic information in a linear tape system or for servo-writing magnetic tapes is also disclosed.
