METHOD FOR EVALUATING INFORMATION REPRODUCTION PERFORMANCE, INFORMATION REPRODUCTION DEVICE, AND INFORMATION RECORDING MEDIUM |
| 摘要 |
A method for evaluating a reproduction performance which reproduces a specific pattern recording signal to measure a reproduced signal noise, and calculates an evaluated value of a reproduction performance on the basis of a frequency characteristic of the measured reproduced signal noise. |

1. A method for evaluating an information reproduction performance, comprising:
reproducing a recording signal of a given pattern by irradiating a recording medium with a light, and measuring a reproduced signal noise; calculating a frequency characteristic related to the reproduced signal noise; calculating an evaluated value on the basis of the frequency characteristic; and evaluating a reproduction performance using the evaluated value.
