PROCESS OF MEASURING SIDE-READING OF ABUTTED-JUNCTION READ HEADS |
摘要 |
Side-reading of an abutted-junction magnetic transducer (10) is measured by constructing (202, 204; 252, 254) at least one microtrack having a transition density. The transducer is moved (206; 256) relative to the microtrack to identify a plurality of positions of the transducer relative to the microtrack where the transducer provides a predetermined response. The side-reading distance of the transducer is identified (216; 260) from the plurality of positions. In one embodiment, a plurality of microtracks are constructed during different iterations (214), each having a different transition density, and the positions of the transducer are identified during each iteration relative to the respective microtrack. In another embodiment, the selected transition density has a fundamental frequency, and the position of the transducer is identified (256) relative to the microtrack where the transducer provides the predetermined response at each of a plurality of harmonic frequencies of the fundamental frequency. |
