Development, micro fabrication, and test of flexible magnetic write head for gentelligent applications

A ''gentelligent component'' inherently stores all information necessary for its distinct identification, reproduction as well as for its manufacturing process and thus has both genetic and intelligent character. For the data storage directly on the components' rough surface a magnetic recording system is required. The goal is to develop a flexible magnetic write head which can adapt its own geometry to the components surface topography and guaranties perfect contact with the surface during the data storage process. This paper presents a new micro fabrication method using the fabrication without a rigid substrate base, double-sided fabrication, adhesive tape application, and high precision drilling. This method simplifies the fabrication process and offers modularity. The write head showed error-free performance after thermal shock test.
