MULTI-PURPOSE NEAR-FIELD TRANSDUCER HAVING A TEMPERATURE COEFFICIENT OF RESISTANCE

摘要

An apparatus includes a writer, an arrangement comprising a plasmonic near-field transducer (NFT) adjacent the writer and comprising a material having a temperature coefficient of resistance (TCR), and a lead arrangement connected to the NFT arrangement. In some configurations, the NFT arrangement includes a heat sink, and the lead arrangement is connected to the heat sink. In other configurations, the lead arrangement is connected directly to the NFT.

1. An apparatus, comprising:
a slider; a writer on the slider; a plasmonic near-field transducer (NFT) having a temperature coefficient of resistance (TCR) and provided on the slider adjacent to the writer, the NFT configured to produce a signal indicative of temperature at the NFT; and circuitry comprising a lead arrangement electrically and directly connected to the NFT; wherein the NFT serves as a heat source for effecting heat-assisted magnetic recording and a temperature sensor.
