ABSTRACT:
A thin film magnetic recording head is provided with a tape bearing surface that has magnetically isolated channels while still providing a maximum continuous surface area with which to engage the media. This can be accomplished by providing spaces in the magnetically permeable thin film that are large enough to prevent cross-talk between the channels, but small enough to prevent significant interference with the moving media. Alternatively, magnetically impermeable thin film spacers can be provided to magnetically isolate each of the channels. The spacers are generally even with the magnetically permeable thin film so as to provide a continuous media-bearing surface.
