    Abstract: This invention relates to an optical recording medium, comprising a substrate, a recording layer, and a reflecting layer where the recording layer comprises at least one dye of formula (I), wherein A1, and A2 are each independently of the other C(CH3)2, O, S, Se, or CH=CH which is unsubstituted or substituted by C1-C5alkyl or benzyl; M1 and M2 are each independently of the other Cr or Co ; L1 and L1' are each independently of the other a ligand of formula (II) or (III); L2 and L2' are each independently of the other and independently of L1 and L1' a ligand of formula (II), (III) or (VI), m is a number from 0.2 to 1.0; and n, depending on m, is a number from 0.0 to 0.8, so that the sum of m and n equals 1.0; p and q are each independently of the other 0 or 1; and Q is CR15, CR15-CR16=CR17 or CR15-CR16=CR17-CR18=CR19. This invention also claims the dyes of formula (I) themselves as well as a process for optically recording, storing or reproducing information using a recording medium of this invention, recording or reproduction preferably being carried out at the wavelength range from 600 to 800 nm.

    Abstract: A dual layer pre-recorded optical disc (12) includes a transparent substrate (14), a partially reflective layer (16), a transparent spacer layer (18), and a highly reflective layer (20). One pattern of data pits (15) is provided on the substrate, adjacent the partially reflective layer, and another pattern of data pits (19) is provided on the spacer layer, adjacent the highly reflective layer. The partially reflective layer may be made of silicon carbide. A substrate-incident beam can be used to read data encoded in either data pit pattern depending on which layer the laser (30) is focused upon. The dual layer disc has twice the data storage capacity of conventional single layer discs.

    Abstract: Recording media having a back coat and a recording layer on opposite sides of a substrate and a super coat adsorbed onto the back coat and/or the recording layer are disclosed. The super coat suitably has a low surface energy. Such media are particularly useful in optical recording applications where the media are in tape form and stored on spools.
