    • The present invention relates to a symbol detection apparatus for detecting the symbol values of a two- dimensional channel data stream recorded on a record carrier, said channel data stream comprising a set of contiguous symbol strips (B) of symbol rows (r) one dimensionally evolving along a first direction and being aligned with each other along a second direction, said two directions constituting a two-dimensional lattice of symbol positions. In order to avoid a substantial loss in detection performance at the edges of a 2D symbol strip in a 2D format, a symbol detector apparatus is proposed comprising: a cross-talk cancellation unit (XTC) for cancellation of radial inter-symbol interference, also known as cross- talk or inter-track interference, present in the first adjacent symbol rows (g01, g02; r1, rN+2)of a symbol strip (B I) from the next but one adjacent symbol row (rb o1, rb02; r0, rN+3) of said symbol strip (B1) by applying for each first adjacent symbol row (g01, g02; r1, rN+2) a cross-talk cancellation between a first adjacent symbol row (g01, g02; r1, rN+ 2) and its neighboring symbol row (rb01, rb02 r 0, rN+3) not belonging to said symbol strip (B 1), and a 2D symbol detector (V) for symbol detection of the symbols of said symbol strip (B1) together with said first adjacent symbol rows (g01, g02; r1, rN+2).

    • The invention provides an efficient reading device in which, even if one radiation beam should fail, no information is lost and the information can still be read out without time-consuming recurring operations. The present invention solves this problem by providing a reading device (Fig. 5A) and a means (Fig. 4) for forming read-out spots (A, B, C, D, E) that are built up by multiple radiation beams from the radiation source (4). This has the advantage that each read-out spot will have energy contributions from different radiation beams and, should one radiation beam break down, the intensity of some of the read-out spots may indeed diminish, but the information can still be read out thanks to the contributions from other radiation beams.
