Structures of storage media for optical storage systems, especially for systems in the near-field configuration to couple radiation between the optical head and the media at least in part by evanescent fields.

Disk mastering based on near-field optical systems

Several embodiments of a method for manufacturing an optical assembly for use in an optical flying head are provided. The optical assembly may include a solid immersion lens and a magnetic coil. Techniques are provided for fabricating the solid immersion lens and the magnetic coil. Techniques are also provided for installing the optical assembly into a slider for the optical flying head. Other embodiments are described in which a solid immersion lens is installed in or is integral with a transparent slider. A magnetic coil may also be installed in these embodiments.

Method of fabricating and integrating an optical assembly into a flying head

Magneto-optical storage media designed for optical storage systems such as disk drives with optical flying heads. Dielectric layers are designed and implemented to maximize optical coupling between the flying optical head and the media and to reduce variations of signals with flight height of the flying optical head.

Storage media for optical storage systems

Optical storage systems based on air-bearing-suspended optical heads in a near-field configuration. Such a system comprises an optical head for reading and writing data and a head positioning system, an optics module including beam relay optics and signal detectors, and a medium holding and loading module to hold an optical medium. An electronic control system is also provided to control the system operation. The optical head includes a near-field lens with a high index of refraction and in a near-field configuration in which the near-field lens has a numerical aperture greater than unity when the spacing between an exit facet of the optical head and a recording layer in the optical medium is a fraction of one wavelength of optical beam.

Optical storage systems with flying optical heads for near-field recording and reading

A system for reading or writing data from or to a bilevel optical recording medium with a flying head. The system includes a head having a slider and a solid immersion lens mounted at least partially within the slider. The solid immersion lens has a partial spherical surface and a substantially flat surface. The head also has an objective lens mounted to the slider. The system also includes a multilevel recording medium. The medium has a first media layer and a first substrate layer adjacent to the first media layer. The medium also has at least one second media layer adjacent the side of the first substrate layer opposite from the first media layer, and a second substrate layer adjacent the side of the second media layer opposite from the first substrate layer. The total effective numerical aperture of the system is greater than one for all layers.

Optical storage system having optical head with a solid immersion lens

A head for a disk drive for reading data from and/or writing data to an optical recording medium, having a slider with a channel surface and an air-bearing surface, an optical clear path through the slider, a solid immersion lens mounted at least partially within the slider, and an objective lens mounted to the slider, such that the distances between the air-bearing surface, the objective, and the solid immersion lens are substantially constant.

Multilayer media and use with flying head having solid immersion lens

Flying head with solid immersion lens partially mounted on a slider

A disk cartridge assembly includes an enclosure, a recording disk mounted for rotation in the enclosure, and an electrostatic cleaning element positioned on an interior surface of the enclosure. The cleaning element engages one side of the disk at least when the disk is at rest and when the disk is rotated at a low speed, and the cleaning element is charged to a high voltage.
