Tape media kiss-contact read verification

摘要

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.

主权项

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 tape by the at least one write element, the read element disposed a distance away from the tape when the supplemental module engages the tape such that a signal resolution measurement value is approximately a minimum acceptable value when the tape is a reference tape; a computer that receives information representative of the electrical signal and determines if a quality metric of the magnetic tape 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.
