| Abstract: | Magnetic printers are subject to serious limitations, due either to the requirement to move the printing head, or to use multiple heads. The purpose of this paper is to describe the principle of a new head which allows a microline to be recorded by scanning a stress in a head which has magnetostrictive pole pieces. Stress characteristics are described and the changes in the magnetic behaviour of two suitable stress sensitive magnetic alloys are given. Finally, the head limitations are discussed. |
