Abstract
To provide an understanding of the relative recording performance of different tapes the paper determines what takes place when the magnetic field from a writing head acts on the particles in the tape. Methods of measuring the following are described: (1) the shape, size, and position of the recorded transition between two oppositely-magnetized regions as a function of writing current; (2) the depth of recording; and (3) recording demagnetization as a function of density.Keywords
