Abstract
An optical read/write head system having a support structure, an optical coupling element and a magnetic data coupling element is disclosed. The optical coupling element is provide on the support structure and is configured to couple optical signal to and from a recording medium. The magnetic data coupling element is also provided on the support structure and is configured to couple magnetic signal to and from the recording medium. The two elements operate in combination to provide more effective reading and writing than with either element alone.
