Flexible Magnetic Reading/Writing System: Characterization of a Read/Write Head

摘要

Intrinsically and locally stored information on components is one of keys technologies for the next industrial revolution. One possibility is an integration of a magnetic storage into a component. Magnetic recording technologies from hard disk drives is adapted and used to create a flexible magnetic reading/writing system that can store information on component surfaces. In this work, a characterization of the flexible read/write head is performed. A transfer characteristic of resistance change of an anisotropic magnetoresistance (AMR) read head is measured inside a homogeneous AC magnetic field. Inductive write tests are performed on a medium with a coercivity of 32kA/m. Generated data tracks are observed by means of a magneto-optic effect. The information gained from those experiments is necessary for gauging performance of the flexible read/write system.
