G11B7/12 - CPC Classification

Classification description:

Recording or reproducing by optical means, e.g. recording using a thermal beam of optical radiation , reproducing using an optical beam at lower power ; Record carriers therefor Heads, e.g. forming of the optical beam spot or modulation of the optical beam

Sub-classes:

G11B7/121 » Protecting the head, e.g. against dust or impact with the record carrier 141
G11B7/122 » Flying-type heads, e.g. analogous to Winchester type in magnetic recording 71
G11B7/123 » Integrated head arrangements, e.g. with source and detectors mounted on the same substrate 205
G11B7/125 » 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 47
G11B7/13 » Optical detectors therefor 145
G11B7/135 » Means for guiding the beam from the source to the record carrier or from the record carrier to the detector 61
G11B7/14 » specially adapted to record on, or to reproduce from, more than one track simultaneously 158
G11B7/22 » Apparatus or processes for the manufacture of optical heads, e.g. assembly 417
