Read/write head with shifted waveguide

摘要: A read/write head for use in data storage drives includes a thermally assisted inductive write section and magnetic read to onto, retrieve from medium. The waveguide formed of core surrounding cladding, positioned between first pole second pole, conduct laser beam heating the optical are offset relative each other at tip, such that they define an overlap region determines written track width. offsetting facilitates manufacturing process since can be made wide enough while still defining tracks with limited
