Abstract:
1. A data recording/reproducing method adapted for performing, onto a recording medium on which a predetermined number of sectors are blocked to form a cluster and first address information including a cluster address corresponding to the cluster and sector addresses corresponding to the sectors is modulated in a predetermined manner and recorded, high-density recording of data by each data sector that is shorter than the sector, the data recording/reproducing method comprising: a step of reproducing the first address information including the cluster address and the sector addresses from the recording medium; a step of generating second address information based on the cluster address in the reproduced first address information and adding identification information specifying a recording area on the recording medium; a step of generating a random number using the generated second address information and the identification information as an initial value of random number; a step of scrambling the data sector on the basis of the generated random number; and a step of recording the scrambled data sector to the recording medium.
