Noiseless magnetic head apparatus and flopply disk drive using the same

摘要

A magnetic read/write head apparatus which may be used in a floppy disk drive for personal computers. The head apparatus is designed to have an improved structure working to eliminate noise components contained in output signals. The structure has magnetic head cores and dummy magnetic head cores. The dummy magnetic head cores work to produce outputs 180° out of phase with outputs of the magnetic head cores, thereby canceling noises contained in the outputs of the magnetic head cores.
