Classification description:

Recording by magnetisation or demagnetisation of a record carrier; Reproducing by magnetic means; Record carriers therefor; Structure or manufacture of heads, e.g. inductive; Structure or manufacture of the surface of the head in physical contact with, or immediately adjacent to the recording medium; Pole pieces; Gap features "Composite" pole pieces, i.e. poles composed in some parts of magnetic particles and in some other parts of magnetic metal layers including at least one magnetic thin film disposed immediately adjacent to the transducing gap, e.g. "Metal-In-Gap" structure
