    摘要： There is disclosed an integrated magnetic transducer for recording and reproducing high frequency electrical signals on a magnetic recording medium and a method of manufacturing the transducer. A silicon substrate has a preferably V-shaped groove with two sides and two ends extending through the silicon substrate. Over the sides of the V-shaped groove a layer of magnetically inductive material is disposed which forms the pole pieces of the transducer. An electrically conductive layer covers this layer of magnetically inductive material and fills the space within the V-shaped groove. Another layer of magnetically inductive material is disposed over the electrically conductive layer. This second magnetically inductive layer completes the magnetic circuit. Means for contacting the electrically conductive layer at opposite ends of the V-shaped groove supply the electrically conductive layer with electrical current. The converging layers of said magnetically inductive material forming the pole pieces of the magnetic transducer are spaced apart at the apex of the V-shaped groove to form a transducer gap.

    摘要： A thin film head is disclosed which is miniaturized to fit within a reduced size window or circumferential slot in a rotary head assembly. The thin film head and window or slot can be made so small that undesired tape cupping into the window or slot is significantly reduced. The thin film head includes a substrate (100) of electrically insulative material. A substantially helical thin film coil structure (220) is situated atop the substrate. A magnetic core (256) extends through an axial region of the coil structure. An elevated, thin film magnetic gap structure is position atop the coil structure. The gap structure includes a first top pole member (350) and a second top pole member (360) which are respectively magnetically coupled to the first and second ends of the magnetic core. A gap region (355) is formed between the first top pole member and the second top pole member.
