  • Adjustment Of The Magnetic Head Position Track Following On Tapes (AREA)

Abstract

PURPOSE: To reduce the abrasion of a magnetic head element by making a dummy head in contact with a magnetic recording medium prior to the magnetic head element and then by making the magnetic head element scan on the scanning track of the dummy head.
CONSTITUTION: To rotary cylinder 2, magnetic head elements 3 and 5 are fitted forming an angle of 180° and dummy heads 4 and 6 in nearly the same shape as magnetic head elements 3 and 5 are fitted at positions preceding head elements 3 and 5. In this case, when cylinder 2 rotates as shown by the arrow, magnetic head elements 3 and 5 are made to scan on tracks on a tape dummy heads 4 and 6 make. In this constitution, frictional heat generate slides between dummy heads and the tape remove slight water molecules on the tape, and consequently abrasion under a high-humidity condition is prevented from increasing as shown by curve A, so that the abrasion can be reduced as shown by curve B.
