The invention provides a magnetoelectric disk, a magnetoelectric memory and a data storage system. The magnetoelectric disc comprises a magnetic tape and a tape winding disc used for winding the magnetic tape, the magnetic tape comprises a data tape and non-data tapes arranged on the two sides of the data tape in the length direction of the data tape, and the non-data tape on at least one side of the data tape is provided with a magnetic head brush. When the magnetic head brush passes through the magnetic head, the magnetic head brush can be used for cleaning the magnetic head.

Disclosed are a magnetic tape unit device, a storage system, a magnetic head cleaning method, a controller, and a magnetic tape, relating to the technical field of magnetic tapes. A magnetic tape integrates a data tape body for storing data and a cleaning tape body for cleaning a magnetic head together, and the cleaning tape body part on the magnetic tape is used to clean the magnetic head in the magnetic tape unit device, without manually pulling out and manually inserting the magnetic tape from and into the magnetic tape unit device, thereby reducing the time consumed for the magnetic tape to be inserted into and pulled out from the magnetic tape unit device, and shortening the cleaning duration of the magnetic head, thus reducing the interruption duration of a data access service caused by cleaning the magnetic head.

A system 100 for the erasure of data from a tape cartridge 110 has a data tape 112, a cartridge memory (CM) chip and a controller 102 in communication with a magnetic head 108, a tape driver 106 and a

The present invention provides a system for the erasure of data from a tape cartridge having a data tape and a CM chip, the device comprising: a controller in communication with: a magnetic head; a tape driver; and an antenna, wherein, when a data cartridge is detected by the controller, the controller is operable to signal to the antenna to determine the CM chip identification data; and, the controller is operable in dependence on the received CM chip identification data to instruct the antenna to overwrite at least a portion of the non-protected memory of the CM chip.

The embodiment of the invention provides a storage device, a tape memory and a storage system, and belongs to the technical field of storage, two sides of a magnetic head of the storage device are provided with cutting edges, the cutting edges can scrape air moving along with a data tape in a read-write state, a low-pressure area is formed between the data tape and the magnetic head to enable the data tape to be close to the magnetic head, and low flying height is achieved. And the read-write efficiency and the read-write precision are improved. The adjusting structures are arranged on the two sides of the magnetic head, each adjusting structure is provided with an arc-shaped face protruding towards the data band, when the data band moves, air is brought into the space between the data band and the adjusting structures to form a gas interval, gas in the gas interval generates a positive pressure effect to support the data band, and the envelope angle and acting force between the data band and the magnetic head are adjusted. The envelope angle and the acting force between the data tape and the magnetic head can be adjusted in a self-adaptive mode through the adjusting structure, it can be guaranteed that low flight height and high read-write efficiency and precision are achieved in the read-write state, the acting force between the data tape and the magnetic head can be reduced in the tape rewinding state, and abrasion between the data tape and the magnetic head is relieved.

The invention discloses magnetic tape unit equipment, a storage system, a magnetic head cleaning method, a controller and a magnetic tape, and relates to the technical field of magnetic tapes. According to the magnetic tape, the data tape body for storing data and the cleaning tape body for cleaning the magnetic head are integrated together, and the magnetic head in the magnetic tape unit equipment is cleaned by utilizing the cleaning tape body part on the magnetic tape, so that the magnetic tape does not need to be manually pulled out of and inserted into the magnetic tape unit equipment, and the time consumed for plugging the magnetic tape into and out of the magnetic tape unit equipment is reduced; the cleaning time of the magnetic head is shortened, so that the interruption time of the data access service caused by cleaning the magnetic head is reduced.
