摘要： Stiction failure of a magnetic recording medium is reduced by forming a lubricant topcoat having a first thickness over the landing zone greater than a second thickness over the data zone, with a sharp transition step having an angle of at least about 70° with respect to a line perpendicular to the surface. Embodiments include depositing a lubricant topcoat at a substantially uniform thickness and reducing the thickness of the lubricant topcoat over the data zone by about 20% to about 80% employing a laser light beam to volatilize the lubricant.

摘要： A magnetic data storage medium is provided that has a substrate surface with regularly spaced, continuous ridges and grooves thereby to enhance the magnetic layer crystallization orientation. Data storage tracks extend longitudinally along the ridges, the grooves between adjacent ridges providing separation between data tracks on either side of each ridge. To form the substrate surface a focused laser beam is continuously applied to the substrate in a path of generally circumferential direction on the disk surface between inner and outer radii of a data storage zone while the substrate is rotated at a relatively constant first speed and the focused beam is moved radially at a relatively constant second speed.

摘要： A magnetic recording medium is formed with enhanced tribological performance by applying a raw, unfractionated lubricant having a wide molecular weight distribution over a disk surface and treating the deposited lubricant with a laser light beam to effect in-situ fractionation of the lubricant to a very narrow molecular weight distribution. Embodiments of the present invention also include laser treating a deposited lubricant to increase the thickness of the bonded lube layer.
