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.
Claims11
An apparatus comprising:
- a production module that is substantially in constant engagement with a magnetic recording medium, the production module including at least one write element that writes magnetic transitions to the magnetic recording medium;
- a supplemental module, including one or more read elements, that periodically physically engages the magnetic recording medium, whereby at least one of the read elements generates an electrical signal corresponding to the transitions written to the magnetic recording medium by the at least one write element;
- a computer that 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;
- and
- in response to determining that the quality metric is not within the defined range, performing a defined action.
