Abstract

A supplemental module that includes one or more read elements periodically engages a magnetic recording medium, and the read elements generate an electrical signal corresponding to transitions written to the magnetic recording medium by a write element. A computer receives information representative of the electrical signal and determines if a quality metric of the magnetic recording medium derived from the electrical signal is within a defined range. If the quality metric is not within the defined range, a defined action is performed by the computer.

First claim

What is claimed is:

1. An apparatus comprising:
a production module that is substantially in constant engagement with a magnetic tape recording medium, the production module including at least one write element that writes magnetic transitions to the magnetic tape;
a supplemental module, including at least one read element, that periodically engages the magnetic tape, whereby the read element generates an electrical signal corresponding to the transitions written to the magnetic…
