摘要： The present invention is concerned with a signal recording device adapted for recording signals on a recording medium in the form of pulse train recording by a rotating magnetic head. As the magnetic head is performing a recording operation, an erasure magnetic head formed in one piece with the magnetic head performs an erasure operation during the reference level period of the pulse train recording to achieve an optimum signal recording with a lesser power consumption.

摘要： The present invention relates to a drive circuit for a rotating erase head (1) used in magnetic recording and reproducing apparatus of rotating head type. Resonance capacitance (8) is added in parallel across terminals (4, 4) of a stationary winding of a rotating transformer (3) for transferring an erase signal to said rotating erase head (1). The resonance capacitance (8) causes parallel resonance at an erase signal frequency (fe) in conjunction with an inductance component (Lr) obtained when the rotating erase head (1) is seen through the rotating transformer (3). Since a parallel resonance current (i r ) thus flows through the rotating erase head (1), a very large erase current (i e ) as compared with a drive current (i d ) supplied by a drive circuit (6) can be obtained. Since the resonance capacitance (8) can be disposed within the drive circuit (6), it can be mounted very simply and the space can be efficiently used. In addition, there is no cost up of a rotating cylinder (2) on which the rotating erase head (1) is disposed at all.

摘要： Systems and methods for sanitizing physical storage in cloud computing and virtual environments. When logical storage is decommissioned in a virtual environment, the underlying physical storage is logically disassociated. However, the underlying physical data blocks remain intact until they are overwritten. Since there is no control over when, or even if, the physical data is ever overwritten, the remaining data is susceptible to compromise. The present disclosure provides a secure erase application that securely erases physical storage associated with to-be deleted resources, such as virtual data stores, virtual images, snapshots and raw virtual disks.

摘要： A method and system for the erasing of data from a non-volatile recording medium includes a non-volatile recording medium controller, a non-volatile recording medium, and a CPU. A data pattern used in an erasure command is sent to the non-volatile recording medium a single time. Consequently, the amount of data transferred to the non-volatile recording medium controller is reduced to a minimum. After receiving the erasure command, the non-volatile recording medium controller overwrites an erasure area with the data pattern.

摘要： Embodiments of the invention provide a method for recording bursts on a disk and a related apparatus. In accordance with an embodiment of the invention, a method for recording bursts on a burst field of a servo sector of a disk comprises generating a first write current corresponding to burst data provided by a write channel circuit, and generating a second write current having a higher frequency than the first write current using a high frequency AC current generator, wherein the high frequency AC current generator is independent from the write channel circuit. The method further comprises selectively applying the first write current to a write head in response to a signal and selectively applying the second write current to the write head in response to the signal.
