Method for providing an electronic lapping guide corresponding to a near-field transducer of an energy assisted magnetic recording transducer |
摘要 |
A method fabricates a transducer having an air-bearing surface (ABS). The method includes providing at least one near-field transducer (NFT) film and providing an electronic lapping guide (ELG) film substantially coplanar with a portion of the at least one NFT film. The method also includes defining a disk portion of an NFT from the portion of the at least one NFT film and at least one ELG from the ELG film. The disk portion corresponds to a critical dimension of the NFT from an ABS location. The method also includes lapping the at least one transducer. The lapping is terminated based on a signal from the ELG.
