<p>A tape head system comprises a read and/or write head 102 having at least one read and/or write element 104 for reading from and/or writing to magnetic tape 112 and at least one electrostatic element 106, 108 arranged adjacent to the read and/or write element. A controller 122 applies a potential 118, 120 to the at least one electrostatic element. A voltage applied to the electrostatic element may be dynamically controlled to maintain a spacing d1, d2, d3, d4. The voltage may be applied so that the magnetic tape contacts the head along a first section 130 and is spaced apart from the head along a second section 138 by an air bearing 132. The head system may include a tensioning unit 128. The electrostatic elements may be formed metal islands integrated into the head surface.</p> |
