22 and adjacent gap 24 the conventional head structure depicted in fig1 has been dramatically improved on and miniaturized over the years since its discovery to present day techniques which include a new method of fabrication known as thin film thin film head construction is depicted in fig2 a d in this method of construction a substrate 36 forms a base over which a first pole piece p 1 38 comprised of a thin film of magnetic material is laid over pole piece p 1 a thin pancake coil 40 is laid wound in a spiral with its leads 42 44 for electrical connection to an appropriate current source not shown as shown in fig2 c a second pole piece p 2 46 overlies one side of the windings comprising coil 40 with a connector 48 attaching pole piece p 2 to pole piece p 1 in an appropriate mechanical orientation to form gap 50 therebetween at the tips 52 54 of pole pieces p 1 p 2 respectively a lead connector 56 is also applied to provide a convenient means for connecting the interior coil lead 44 to an external current source not shown as shown in fig2 d the windings of coil 40 surround pole piece p 2 to induce a magnetic flux in the gap 50 formed between pole tips 52 54 the present.
