Magnetic head position reference system

摘要

A position reference system is disclosed which provides an indication of the amount of mistracking of a magnetic head while the latter is stationed in its normal operating environment. The system is also capable of providing an indication of the spacing tolerances of a multi-core head. A special tracking medium is recorded against which the position of the head is compared. The sensitivity of the disclosed system permits a determination of mistracking as well as corrective adjustments to be made against visual observation only.
