Thin film heating device in a write gap
An apparatus, in accordance with one embodiment, includes a write transducer having a pair of writer poles having pole tips, the pole tips defining a write gap therebetween. A thin film device is positioned at least in part in the write gap for raising a local temperature of the write gap. Electrical connections for causing a current to pass through the thin film device are also present. A method, in accordance with one embodiment, includes passing a current through a thin film device positioned at least in part in a write gap defined between pole tips of writer poles of a write transducer for causing heating of the thin film device. A level of the current is changed in response to detection of a predefined condition.
Management of head and media dimensional stability
An apparatus, according to one embodiment, includes a magnetic head having servo readers of known pitch, a drive mechanism for passing a magnetic recording tape over the magnetic head, and a controller electrically coupled to the magnetic head. The controller is configured to measure, using signals from the magnetic head, a servo band difference at various locations along a length of the magnetic recording tape. The controller is also configured to cause storage of servo band difference information about the servo band difference measurements in association with the magnetic recording tape.

MANAGEMENT OF HEAD AND MEDIA DIMENSIONAL STABILITY
A method for characterizing a magnetic recording tape, according to one approach, includes measuring, using a magnetic head having servo readers of known pitch, a servo band difference at various locations along a length of a magnetic recording tape. The servo band difference measurements and/or derivatives thereof are stored in association with the magnetic recording tape. This procedure creates a characterization of the magnetic recording tape that is useful for assessing aging of the magnetic recording tape, as well as improving subsequent reading and/or writing operations.
