    摘要： A system lead-in area, data lead-in area, data area, and middle area are sequentially arranged from an inner circumference of layer 0. A system lead-out area, data lead-out area, data area, and middle area are sequentially arranged from an inner circumference of layer 1. A guard track zone is arranged in the data lead-out area. A reference code zone, R physical format information zone, recording position management zone, and drive test zone are arranged in the data lead-in area of the layer 0 corresponding to the guard track zone. Padding of the guard track zone of the data lead-out area is performed after padding of the drive test zone of data lead-in area and recording of the recording position management zone, the reference code zone of the data lead-in area, and the R physical format information zone of the data lead-in area.

    摘要： According to one embodiment, an information reproduction apparatus includes an information acquisition unit, an error detection unit, and a control unit. The information acquisition unit is configured to irradiate a reference beam, convert the reference beam into a luminance signal, and output the luminance signal when reproducing an information recording Medium. The error detection unit is configured to detect at least one selected from a first error and a second error by extracting a feature extraction quantity from the luminance signal. The first error is of an irradiation angle of the reference beam. The second error is of at least one selected from a temperature and a wavelength of the reference beam. The control unit is configured to control at least one selected from the irradiation angle and the at least one selected from the reproduction temperature and the wavelength of the reference beam using the second error.
