| 英文摘要 | A method of controlling power in an optical disc apparatus is provided. A method of controlling power in an optical disc apparatus includes: measuring a temperature of an inside of the optical disc apparatus; calculating, based on the measured temperature, a driving value with which a laser diode (LD) outputs target power; and driving the LD with the calculated driving value. The driving value uses a function in which a temperature acts as a variable and may be calculated for a read channel and a write channel in a divided manner. In the read channel, a driving value of read power in a read mode and a driving value of read power in a record mode may be calculated using different functions, and in the write channel, a driving value of at least one segment of record power divided into two or more segments may be calculated using different functions. |
