Abstract: A thermally-assisted recording (TAR) disk drive operates by turning on write current prior to the application of heat to the recording layer by the near-field transducer (NFT). In a TAR disk drive that uses thermal fly-height control (TFC), TFC power is at a first power level that keeps the write pole at a predetermined fly-height. The write current is then turned on, either simultaneously with or after a reduction in TFC power. The write pole then reaches its optimal fly-height as a result of the combination of write pole protrusion caused by the write current and retraction of the write pole caused by the reduction in TFC power. After the write pole has reached its optimal fly-height, heat is applied to the recording layer by the NFT. The combination of write current and heat causes writing to occur at the optimal write pole fly-height.

Abstract: In a nonreturn valve having a tubular body, which can be installed in a vertical section of an exhaust line, a valve seat, formed within the tubular body, for at least one float, and at least one circumferential groove, which is open in the downstream direction, the intention is to make available a solution by means of which it is possible to provide a nonreturn valve that is simple, advantageous in terms of production engineering and has a particularly high performance, and to do so in a way which is simple in terms of design and is economical. This is achieved by virtue of the fact that the circumferential rim of the at least one float projects radially over the radially inner circumferential wall section and has an axial lip facing upstream, which extends into the circumferential groove in the axial direction when the at least one float is resting on the valve seat.
