摘要： A magnetic head and method for making same which can be used for formatting or writing servo tracks or data on a tape. In one example, the magnetic head may include a magnetic thin film layer; at least one gap defined in the magnetic thin film layer; and at least one secondary sub-gap structure within the magnetic thin film layer, the at least one gap positioned proximate the at least one secondary sub-gap structure. Through the use of the secondary sub-gap structure, the gap (i.e. a record gap or channel) can be made thinner than in conventional heads.

摘要： A method of recording servo information includes writing servo information in a data storage medium using a compound magnetic recording head. The compound magnetic recording head has a substrate including first and second magnetically permeable substrate portions and a substantially non-magnetic member interposed between the first and second magnetically permeable substrate portions. A magnetically permeable layer is provided over the first and second magnetically permeable substrate portions of the substrate and includes first and second writing gap features associated with the first and second substrate portions. The writing gap features are formed using a patterned mask layer over the magnetically permeable layer, wherein the patterned mask layer comprises first and second patterned gap features corresponding to the first and second writing gap features.

摘要： A solid state device is formed through thin film deposition techniques which results in a self-supporting thin film layer that can have a precisely defined channel bored therethrough. The device is useful in the chacterization of polymer molecules by measuring changes in various electrical characteristics as molecules pass through the channel. To form the device, a thin film layer having various patterns of electrically conductive leads are formed on a silicon substrate. Using standard lithography techniques, a relatively large or micro-scale aperture is bored through the silicon substrate which in turn exposes a portion of the thin film layer. This process does not affect the thin film. Subsequently, a high precision material removal process is used (such as a focused ion beam) to bore a precise nano-scale aperture through the thin film layer that coincides with the removed section of the silicon substrate.

摘要： A thin film magnetic recording head is fabricated by forming a substrate from opposing ferrite blocks which have a ceramic member bonded between them. This structure is then diced to form a plurality of columns, wherein each column has a ferrite/ceramic combination. Each column represents a single channel in the completed head. A block of ceramic is then cut to match the columned structure and the two are bonded together. The bonded structure is then cut or ground until a head is formed, having ceramic disposed between each channel. A ferrite back-gap is then added to each channel, minimizing the reluctance of the flux path. The thin film is patterned on the head to optimize various channel configurations.
