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. 1. A slider having a leading edge , a trailing edge , an air-bearing surface (ABS) , and read/write heads proximate the trailing edge , the slider comprising:a micro-pattern of SAM material on the ABS, the micro-pattern comprising discrete unconnected features.2. The slider of claim 1 , wherein the micro-pattern comprises dots and the SAM is oleophilic and/or hydrophilic.3. The slider of claim 2 , wherein the dots are circular.4. The slider of claim 2 , wherein the dots are hexagonal.5. The slider of claim 2 , wherein the dots are evenly spaced.6. The slider of claim 2 , wherein the dots have no dimension greater than 10 micrometers.7. The slider of claim 6 , wherein the dots have no dimension greater than 8 micrometers.8. The slider of claim 6 , wherein the dots have no dimension greater than 6 micrometers.9. The slider of claim 1 , wherein the micro-pattern comprises lines and the SAM is oleophobic and/or hydrophobic.10. The slider of claim 9 , wherein the lines are straight.11. The slider of claim 9 , wherein the lines are evenly spaced.12. The slider of claim 9 , wherein the lines have a thickness no greater than 10 micrometers claim 9 , in some implementations no greater than 6 micrometers.13. A slider having a leading edge claim 9 , a trailing edge claim 9 , an air-bearing surface (ABS) having rails and recessed areas claim 9 , and read/write heads proximate the trailing edge claim 9 , the slider comprising SAM material on the recessed areas of the ABS claim 9 , and no SAM on certain areas claim 9 , such as the rails.14. The slider of claim 13 , wherein the SAM is continuous.15. The slider of claim 13 , wherein the SAM is ...
