摘要： A method of erasing a servo pattern of a hard disk drive includes reading a servo pattern recorded on a disk, generating an erase pattern to erase the servo pattern based on the servo pattern obtained in the reading of the servo pattern, and erasing the servo pattern by using the erase pattern while the disk is rotated. The servo pattern recorded on the hard disk drive may be uniformly erased. Also, a stabilization time to stabilize a read/write head after the position control of the read/write head that is needed when a servo writer is used may be avoided so that a time to erase a servo pattern may be reduced.
摘要翻译：擦除硬盘驱动器的伺服模式的方法包括读取记录在盘上的伺服模式，根据在伺服模式的读取中获得的伺服模式产生擦除模式以擦除伺服模式，并擦除伺服模式通过在盘旋转时使用擦除图案。记录在硬盘驱动器上的伺服模式可能被均匀地擦除。此外，可以避免在使用伺服写入器时所需的读/写头的位置控制之后稳定读/写头的稳定时间，从而可以减少擦除伺服模式的时间。

摘要： A guarantee processing method guarantees the data of an adjacent track in the case of a write fault when there is a possibility of an off track write. Even if a write fault is detected or an offset read retry is successful, a rewrite for guaranteeing an adjacent track is not executed immediately. The possibility of an off track write is judged by the movement of the head, and only the sector which is difficult to read due to the off track write is rewritten.

摘要： A disk drive includes a rotatable data storage disk, a transducer, an actuator, and a controller. The transducer is configured to read and write data on the disk. The actuator is configured to position the transducer relative to defined portions of the disk. The controller is configured to write a predetermined magnetic polarity pattern on a buffer portion of the disk to erase data thereon. The controller also determines whether the disk drive has reached a threshold operating temperature, and to selectively direct data from a host device, which is addressed for an associated original block address on the disk, to be written to the buffer portion of the disk when the disk drive has not reached the threshold operating temperature. The controller later copies the data from the buffer portion of the disk to the original block address on the disk and then erases the data from the buffer portion of the disk.

摘要： Methods and apparatus for erasing magnetic tape are described. The tape to be erased is fed through an erasure unit that includes an array of magnetic elements. The array of magnetic elements includes a first set of magnetic elements and a second set of magnetic elements. The magnetic fields for the respective first and second sets of magnetic elements have opposite polarity, as seen by the tape as it feeds through the erasure unit. The fields seen by the tape as it feeds through the erasure unit decrease in intensity.

摘要： A method to erase a magnetic tape, where the magnetic tape is first mounted in a magnetic tape in a tape drive, where that magnetic tape includes a physical beginning of tape (nullPBOTnull), a physical end of tape (nullPEOTnull), and information written thereon between the PBOT and the PEOT. The method then establishes one or more critical areas located on the magnetic tape, attempts to erase the information, and determines if each of the one or more critical areas have been erased. In the event each of said one or more critical areas have not been erased, Applicants' method provides an error message.
