摘要 |
A disc-shaped recording medium (32) has compressed audio data recording therein. The inner diameter (dI) of a data recording region (RA) is set to a value in a range of 28 to 50 mm. The outer diameter (dO) of the data recording region is set to a value corresponding to the inner diameter such that, for the lower limit value of 28 mm for the inner diameter the outer diameter is in the range of 58 to 62 mm, whereas for the upper limit value of 50 mm for the inner diameter the outer diameter is in the range of 71 to 73 mm. <IMAGE> |
