Abstract
A method for positioning an information processing head at a predetermined position on a recording medium includes detecting a predetermined magnetization pattern on a magnetic material having a predetermined positional relation to a recording region of the recording medium by a magnetization detector having a predetermined positional relation to the information processing head, generating a signal indicative of a relative position of the information processing head with respect to the recording medium based on a result of the detecting step and moving the information processing head and the recording medium relatively to position the information processing head at the predetermined position with respect to the recording medium based on the generated signal, and a process for forming a cantilever-type probe capable of indicating a magnitude of a magnetic force between the probe and a recording medium and capable of performing at least one of a recording operation and a reproducing operation on the recording medium.
