Abstract
A tape head system includes a read and/or write head having at least one read and/or write element configured to read from and/or write to magnetic tape and at least one electrostatic element arranged adjacent to the read and/or write element; and a controller configured to apply a potential to the at least one electrostatic element.
Claims12
A tape head system comprising:
- a read and/or write head having at least one read and/or write element configured to read from and/or write to magnetic tape and at least one electrostatic element arranged adjacent to the read and/or write element, wherein the at least one electrostatic element and the at least one read and/or write element form a cluster, wherein multiple clusters are arranged on the head;
- and
- a controller configured to apply a potential to the at least one electrostatic element, and to control the at least one electrostatic element of each cluster so that the magnetic tape only contacts or is arranged in close relationship with the head along first sections of the head and is spaced apart from the head at second sections of the head in between the first sections by an air bearing respectively, the head being formed with a bevel at at least one of the second sections.
A method for operating a tape head system, comprising a read and/or write head having at least one read and/or write element configured to read from and/or write to magnetic tape and at least one electrostatic element arranged adjacent to the read and/or write element, wherein the at least one electrostatic element and the at least one read and/or write element form a cluster, wherein multiple clusters are arranged on the head, the method comprising:
- applying, with a controller, a potential to the at least one electrostatic element, and controlling the at least one electrostatic element of each cluster so that the magnetic tape only contacts or is arranged in close relationship with the head along first sections of the head and is spaced apart from the head at second sections of the head in between the first sections by an air bearing respectively, the head being formed with a bevel at at least one of the second sections.
