Disk for a disk clutch or brake, disk clutch or brake with such a disk, and a method for producing such a disk

A disk (2) for a disk clutch or brake (4) comprising a first friction surface (28) and a second friction surface (34) facing away from the first friction surface (28), in which recesses or grooves (40, 42, 44) are provided, characterized in that a first type of recesses or grooves (40), which is generated by a material shaping or a material casting or a non-material removing first manufacturing method, is provided in the first friction surface (28), and a second type of recesses or grooves (42), which is generated by a material-removing second manufacturing method, is provided in the second friction surface (34),

• characterized in that the first friction surface (28) has no recesses or grooves (42) of the second type and the second friction surface (34) has no recesses or grooves (40) of the first type, wherein only the first type of recesses or grooves (40) is provided in the first friction surface (28), and only the second type of recesses or grooves (42) is provided in the friction surface (34)
• and characterized in that the first type of recesses or grooves (40) has a shallower depth than the second type of recesses or grooves (42).
