Monitoring head wear |
| 摘要 |
A method, executed by a computer, for monitoring head wear includes reading from a cartridge a high frequency pattern and a low frequency pattern, determining a first read amplitude corresponding to the high frequency pattern and a second read amplitude corresponding to the low frequency pattern, and determining a head wear metric according to the first read amplitude and the second read amplitude. A computer program product and computer system corresponding to the above method are also disclosed herein. |
