Magnetic head arm having thermal compensation member for correcting tracking error |
摘要 |
A magnetic head for use in a magnetic disk drive. An arm included in the head is partly constituted by a member which is different in the coefficient of thermal expansion from the other portion of the arm. This is successful in readily correcting a tracking error ascribable to the thermal expansion of the arm despite the varying ambient temperature.
