A method for texturing a substrate for a magnetic disk comprises abrading the substrate using nano-sized diamond particles (e.g. having a diameter less than or equal to 20 nm). A magnetic layer is then deposited over the substrate. Even when the texture is extremely smooth (e.g. less than about 2.2 Å Ra), the disk still exhibits good Hc and MrT orientation ratios, SNR and PW50.
