  • Information storage device, information recording/reproducing device, and power consumption management method
    Patent number: 8024589
    Abstract: 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.

  • Information reproduction apparatus, information reproduction method and information recording medium for a rotation control program
    Publication number: 20050007918
    Abstract: An information reproduction apparatus is provided with: a drive device which rotates an information recording medium in order to read out predetermined information from the information recording medium; a reading device which reads out the information on the basis of commands issued from an external host; a measurement device which measures a command interval of the commands; and a rotation control device which controls a rotation speed of the driving device on the basis of the command interval measured by the measurement device.
