Abstract
A transducer having an external contact surface includes a writer and a contact member. The writer has a portion extendable relative to an adjacent portion of the external contact surface. The contact member surrounds at least a portion of the extendable writer portion and is spaced from the extendable writer portion. The coefficient of thermal expansion of the contact member is approximately equal to the coefficient of thermal expansion of the extendable writer portion.
