recording medium fig1 is a cross sectional view illustrating access by a probe in a recording medium according to an exemplary embodiment of the present invention in the case of a conventional recording medium as illustrated in fig1 a case when a probe 90 accesses first and second recording layers 80 and 82 will be considered the probe 90 searches for and accesses the first recording layer 80 and then a predetermined operation is performed subsequently the probe 90 searches for the second recording layer 82 in order to access the second recording layer 82 that is the probe 90 should search for each recording layer one by one in order to access it however in the case of a recording medium according to an exemplary embodiment of the present invention at least the two recording layers 44 and 46 are disposed on opposite surfaces of the supporting layer 42 accordingly when the probe 90 accesses the recording layer 44 of the two recording layers 44 and 46 the probe 90 can access the recording layer 46 by only moving across the upper surface of the supporting layer 42 that is it is unnecessary to search for the subsequent recording layer when the probe 90 has already accessed one of two adjacent recording layers which are opposite to each other and where the supporting layer 42 exists.
