ABSTRACT:
The substrate of a magnetic recording medium is laser textured using a continuous wave laser light beam and microfocusing lens system to form a laser textured data zone comprising a plurality of substantially uniform concentric microgrooves. In an embodiment, the microfocusing lens system comprises an array of horizontally and vertically spaced apart microfocusing lenses, each optically linked to a fiber optic cable.
