Abstract: The disclosure concerns a method of processing Internet telephony messages at gateway computer such as an IBM RISC/6000 system, comprising the steps of: receiving an Internet telephony message in a first compression scheme from a computer running an Internet telephone software application which uses the first compression scheme; converting the Internet telephony message into a compression scheme optionally via an intermediate format; sending the Internet message telephony to another computer running another Internet telephone software application using the second format.

Abstract: A thin film low profile write head is provided which has first and second pole pieces which are magnetically connected in a pole tip region and at a back gap. The pole tip region is located between the head surface and a zero throat height and the head has a body region which is located between the zero throat height and the back gap. A plurality of insulation layers are located above the first pole piece in the body region. Each of the insulation layers has an apex where the insulation layer commences and each insulation layer extends from its apex toward the back gap. The plurality of insulation layers typically includes first, second and third insulation layers. In the preferred embodiment the apex of the second insulation layer is located at and defines the zero throat height of the head. This enables a very narrow track width second pole tip to be constructed simultaneously with the second pole piece using ordinary photolithography processes. Further it enables the insulation layers, the coil layer and the second pole piece to be thinner than prior art layers.
