    摘要: The present invention relates to a domain expansion storage medium and manufacturing method with improved readout performance. The substrate of the storage medium and/or its storage layer is processed to define a predetermined shape of magnetic domains, adapted to the front of the thermal reading profile. In particular, reversed crescent shaped domains flipped in the track directions are defined. This allows improved resolution and jitter values.

The second light transmitting layer (118) comprises a first side (110) which is optically coupled to the first light transmitting layer (120) to receive light from the first light transmitting layer (120). The second light transmitting layer (118) further comprises a second side (106) which is substantially opposite the first side (110) to emit the received light into another optical medium. The second light transmitting layer (118) further comprises a geometrical structure (116) at the second side (106) to obtain a decreasing light emission with increasing light emission angles (9a) with respect to a normal (112) to the first side (110).

    摘要: Multi layer near-field optical recording using a moderate numerical aperture (NA) is superior to the high-NA (NA=2.0) first-surface single-layer technique. The use of very flat and thin spacer layers limits spherical aberration due to difference in layer depth. The thin spacer layers may have a high refractive index because their thickness allow for a relatively high absorption constant. This makes possible in principle an m-layer system, e.g. m=4, with NA=1.6 which may include a flat, protective cover layer. Further a medium for use in such a system is described.

    摘要: For optical data storage applications a near field optical system can be used. In near field optical systems an accurate alignment of a solid immersion lens with respect to a disc surface is crucial. The correction of a tilt between the lens and the disc is performed by use of auxiliary beams. By comparing the gap signal for the auxiliary beams the air gap height and disc tilt can be determined.
