Sheets for formation of patterns and methods for forming and fixing

In a magnetic head with a slider, there are provided a head core made of a magnetic material having a first sliding surface for slidably contacting with a magnetic recording medium and at least one recording and reproducing gap defined on the sliding surface, a slider having a second sliding surface for slidably guiding the magnetic recording medium. The slider is connected to one side wall of the magnetic head core by an adhering material. A recess is defined on the slider along the entire length of the peripheral portion of one side wall of the magnetic head core. Chamferred parts are formed on the corner of the first sliding surface and the side wall of the magnetic head core.

Bar code label

A magnetic head having a pair of core halves each combined through a magnetic gap, each of the core halves comprising a core base having slanted side surfaces on the side opposing to the magnetic gap and a magnetic thin layer formed on the surfaces of the core base on the side opposing the magnetic gap with magnetic material of high saturation magnetic flux density, the minimum value of the sum of products of vertical cross sectional areas of the respective magnetic paths of each of the core halves except for the path of the magnetic gap and the respective saturation magnetic flux densities of the respective parts is greater than the product of the area of the magnetic gap and the saturation magnetic flux density of the magnetic thin layer.
