A recording head has a magnetic write transducer having a first crosstrack width operable to write a single track of data at a time to a magnetic disk. The recording head also has a magnetic erase transducer separate from the magnetic write transducer. The magnetic erase transducer has a second crosstrack width operable to simultaneously erase multiple tracks of data at from the magnetic disk

In an approach, a processor determines that an inactive data area is present at end-of-tape (EOT) of a tape. A processor, responsive to determining that the inactive data area is present at EOT, securely erases the inactive data area that is present at EOT by overwriting data located at the inactive data area with different data.

A method of erasing data from a data storage apparatus comprising a memory, the method comprises writing a known data pattern to a plurality of known memory locations of the data storage apparatus, causing the data storage apparatus to perform a data erasure procedure, reading data stored at the known memory locations after completion of the data erasure procedure, comparing the read data and the data of the known data pattern, and determining a verification result based at least in part on the result of the comparison between the read data and the data of the known data pattern.

Provided are a computer program product, system, and method for indicating tracks as erased without deleting data for the tracks. In response to receiving erase commands to erase tracks in the storage, indicating the tracks as erased without performing an erase operation on the tracks subject to the erase command. Data in the storage for the tracks indicated as erased remains in the storage while requests are directed to the tracks indicated as erased. A command is received indicating an operation with respect to a target track. The operation to proceed is permitted with respect to the target track in response to determining that the target track is not indicated as erased. An alternate operation is performed providing a result different from the operation indicated in the command in response to determining that the target track is indicated as erased.

A rapid demagnetization method based on characteristics of magnetic media. In the method, basic information is obtained by a recognition module of magnetic media by means of multi-source sensing collaboration. The magnetic medium is identified by using a data processing technology and a magnetic medium identification algorithm, and then the characteristic information is extracted. Optimized set values of demagnetization parameters are obtained by a demagnetization parameter optimizing and setting module based on a demagnetization optimizing model. Demagnetization parameter set values are tracked by a closed-loop control module of a demagnetization magnetic field in combination with domain expert knowledge by using a closed-loop control mechanism integrated with a magnetic field control algorithm, a charging-discharging device, a magnetic field generating device, a magnetic field sensor and an environmental sensor, completing the rapid demagnetization of the magnetic medium.

Provided are a tape erase element, tape erase device, and method for forming a tape erase element to erase content of a tape medium. The tape erase element comprises a housing forming a gap extending along a length of an outer surface of the housing. The gap extends from the outer surface of the housing to open into an inner space formed within the housing. A magnet is positioned within the inner space of the housing and having a surface extending across the gap. The magnet produces a magnetic flux that extends through a tape contact zone extending across a portion of the outer surface of the housing and the gap to erase content on the tape medium as the tape guide rollers guide the tape medium across the housing through the tape contact zone.
