Abstract: In the field of coding/decoding in telecommunications networks, an error correcting decoder and associated decoding method are adapted to a mesh network.In particular, the system for the decoding of a plurality of coded copies of a data word includes at least a first decoding stage with: a plurality of soft decision decoders, each decoder being arranged for decoding a coded copy received as decoder input, and a graph-based decoder comprising a plurality of nodes, each node of said graph-based decoder receiving the soft output value from a corresponding decoder and the graph-based decoder determining a decoding value of said data word on the basis of said soft output values.

Abstract: A process and device for focussing a light energy beam on a data carrier comprising sites fromed of virgin areas free from any data recording provided along tracks and serving as reference plane for said focussing. In a preferred variation, these areas are preceded by flags associated with a specific code. Control is achieved by measuring the deviation between the plane of focussing of a beam into a spot scanning the tracks and the reference plane formed by the surface of the virgin areas. Between two passages of these areas of the measurements are stored. The focussing error signal is obtained by filtering these measurements.
