G11B0007013000 for discrete information, i.e. where each information unit is stored in a distinct location 1
G11B0007080000 Disposition or mounting of heads or light sources relatively to record carriers 1
G11B0007085000 with provision for moving the light beam into, or out of, its operative position. 1
G11B0007090000 with provision for moving the light beam or focus plane for the purpose of maintaining alignment of the light beam relative to the record carrier during transducing operation, e.g. to compensate for surface irregularities of the latter or for track following 1
G11B0007095000 specially adapted for discs, e.g. for compensation of eccentricity or wobble 1
G11B0007100000 Interchangeable mountings, e.g. for replacement of head without readjustment 1
G11B0007120000 Heads, e.g. forming of the optical beam spot or modulation of the optical beam (disposition or mounting of head elements within housing or with provision for moving of light source, optical beam or detector, irrelevant to the transducing method G11B0007080000) 1
G11B0007121000 Protecting the head, e.g. against dust or impact with the record carrier 1
G11B0007122000 Flying-type heads, e.g. analogous to Winchester type in magnetic recording 1
G11B0007123000 Integrated head arrangements, e.g. with source and detectors mounted on the same substrate 1
G11B0007124000 the integrated head arrangements including waveguides 1
G11B0007124500 the waveguides including means for electro-optical or acousto-optical deflection 1
G11B0007125000 Optical beam sources therefor, e.g. laser control circuitry specially adapted for optical storage devices; Modulators, e.g. means for controlling the size or intensity of optical spots or optical traces 1
G11B0007126000 Circuits, methods or arrangements for laser control or stabilisation 1
G11B0007126300 Power control during transducing, e.g. by monitoring 1
