摘要： The present disclosure includes methods of using a sacrificial, protective head overcoat during the manufacture of sliders. In some embodiments, the final trailing edge topography of the transducer devices is formed before applying the sacrificial, protective head overcoat. In some embodiments, the final trailing edge topography of the transducer devices is formed after removing the sacrificial, protective head overcoat.

摘要： Methods for providing a SAM (self-assembled monolayer) coating on a slider and subsequently removing a portion of the SAM coating. In one implementation, the method includes applying a SAM coating on at least a first surface of a slider and on a second surface of the slider opposite the first surface, and removing at least a portion of the SAM coating from the second surface by irradiating the second surface with UV radiation in a wavelength range of 100-200 nm.

摘要： A slider for a data recording device such as a disc drive. The slider has a pattern, which can be a micro-pattern, of SAM material on the air-bearing surface (ABS). The pattern comprises discrete unconnected features, such as dots or lines, that may or may no cover the entire ABS. Methods of micro-printing on the ABS are also provided.

摘要： An air-bearing surface of a slider is coated with a photoresist having a high optical absorbance at or near an operational wavelength of the slider. Light is directed at a target wavelength through an entry of a waveguide integrated into the slider. The light exiting the waveguide forms a feature through the photoresist, the feature proximate a near-field transducer of the slider. A sub-micron pattern is formed using the feature.
