摘要： In a pulse width modulated read signal channel for an optical disk drive, a data-transition threshold is maintained for data detection by a threshold tracking circuit that estimates the amplitude centerline data-transition threshold from the most recent maximum and minimum values of the read signal waveform. To improve the accuracy of the response of the centerline estimator, the threshold is increased or decreased based on the phase error at each read signal transition through the data-transition threshold. In addition, defects in the optical recording media are detected, and a defect present signal is used to inhibit the transition phase error input to the centerline estimator. This prevents the estimator from moving the threshold to an incorrect stable level. In addition, the defect present signal boosts the error feedback in the centerline estimator. The estimator then more quickly follows the read signal waveform. As a result, the estimator reacquires the centerline of the waveform after the read head moves past the defect without retriggering the defect detection circuit.

摘要： A system and computer program product are provided for utilizing target of opportunity to perform at least one special operation while a removable storage medium is mounted within a data storage drive for another purpose. The system for recognizing a target of opportunity comprises a tape drive. The tape drive receives a command to mount a tape cartridge in the tape drive, and in response the tape drive mounts the tape cartridge in the tape drive. The tape drive determines if at least one special operation may be performed. If it is determined that at least one special operation may be performed, the tape drive recognizes that a target of opportunity exists. In response to determining that at least one special operation may be performed, the tape drive sends a first notification that the tape drive is to remain in a not ready state. The tape drive performs the at least one special operation, and in response to performing the at least one special operation, the tape drive sends a second notification that the tape drive is in a ready state or an error state.
