| 摘要 |
An information recording/reproducing device, wherein a power management mechanism for a serial ATA interface connecting between an optical disk drive and a host computer has a steady-state power mode (PHYRDY) and a power-saving mode (Partial state, Slumber state) to keep power consumption lower than the steady-state power mode, while a power management mechanism built into the optical disk drive has a steady-state power mode (active state) and a power-saving mode (inactive mode) to keep power consumption lower than the steady-state power mode. The optical disk drive controls transition of the power consumption modes of the power management mechanism for a serial ATA interface in accordance with current power consumption mode of its internal power management mechanism. |
