Abstract: A device for recording information on a storage medium (11) is arranged for formatting the storage medium. The device has receives a format command according to a protocol (ATA/ATAPI). The device has formatting means for formatting a multilayer storage medium according to the format command. The formatting includes recording, on each layer (L0, L1) of the multilayer storage medium, a first control zone (71, 72) at a first radial position on the layer and a second control zone (73, 74) at a second radial position on the layer for forming an annular data zone of a selected size between the control zones. If the format size is smaller than a maximum available size on the storage medium, the control zones are positioned on substantially equal radial positions for forming radially corresponding annular data zones (75, 76). The required format size equals the sum of the selected sizes of each annular data zone.
