A recording medium is provided which comprises (a) a first recording layer; (b) a second recording layer provided in contiguity to the first recording layer; and (c) a separation layer for spatially separating the first and second recording layer. The first recording layer has a sufficient film thickness not to permit the recording to be effected on the second recording layer, while the recording operation is performed on the first recording layer, and the recording operation is effected on the second recording layer at positions corresponding to defective portions in the first recording layer.
