Glide head for detecting defects on a disk surface |
摘要 |
A glide head for testing the surface of a magnetic disk includes a slider, a type 2 piezo-electric transducer mounted on the slider, and a type 1 piezo-electric transducer mounted on the type 2 piezo-electric transducer. The piezo-electric transducers are mechanically coupled to one another but not electrically coupled to one another. The electrical voltage provided by the type 2 piezo-electric transducer is more sensitive to magnetic disk surface defects than if the type 1 piezo-electric transducer were not present.
