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 method of separating a sheet of a brittle material into portions by means of laser-scribing, comprising steps of: (a) providing a sheet of a brittle material having first and second opposing major surfaces separated by a thicknesst; (b) providing a source of laser energy adjacent said first surface, adapted for supplying a focussed beam of laser energy converging to a focal spot in a plane parallel to the first surface; (c) irradiating the sheet of brittle material with the focussed beam of laser energy, the plane of the focal spot of the beam initially being positioned within the sheet just below the first surface; and (d) continuing irradiating while simultaneously providing relative movement between the focal spot of the laser beam and the sheet to move the focal spot at a pre-selected rate and path extending over the first surface, and moving the depth of the plane of the focal spot at a pre-selected rate through a major portion of thickness t of the sheet to form a micro-crack zone extending along the pre-selected path from just below the first surface to a shallow depth just below the second surface.

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： Laser-scribing brittle substrates along a curvilinear path is effected by impinging and moving at least two laser light beam spots along the substrate surface, the first spot preheating the substrate and the second smaller spot heating the substrate to the laser-scribing temperature below the softening temperature of the substrate. Embodiments include forming dual spots employing a crystal material or employing dual fiber optic cables each optically linked to a lens. In another embodiment, three spot lasers spots are formed employing a three-spot diffractive lens, the third spot formed behind the second laser-scribing spot and heating the surface to a temperature lower than the laser-scribing temperature. Embodiments further include laser-scribing substantially circular glass, ceramic or glass-ceramic substrates for magnetic recording media.

摘要： A magnetic recording medium is formed with a distribution of laser micromachined servo-marks in the form of pits or indentations with an attendant reduction in servo-tracking area and increased data-recording speed. Embodiments include laser texturing to form a radially extending linear or arcuate series of circular or elliptical pits across the data zone. The micromachined servo-marks are detected by mechanical or electrical means and denote the beginning and end of magnetically recorded servo-information in a data track, thereby enabling accurate and timely positioning of the read/write head by the servo-controller of the hard drive.
