    • A media drive, a computer system, and a media drive control method, in which insertion/ejection of a removable medium into/from a media drive being in a sleep mode that is a power saving mode of operation can be detected, and the power consumptions of the media drive and host computer can be still more saved. When a CD-ROM drive (2) being in the sleep mode detects a change of status of a CD-ROM, such as insertion or ejection thereof, it notifies a personal computer (1) of the CD-ROM status change by using a hardware interrupt signal without polling. Thus, the status of CD-ROM insertion/ejection into/from the CD-ROM drive (2) can be grasped from the personal computer (1) to place the CD-ROM drive (2) in the sleep mode when the CD-ROM needs not be driven or in a normal mode of operation when it needs to be driven.
    • 可以检测介质驱动器,计算机系统和介质驱动器控制方法,其中可移除介质插入/从介质驱动器处于处于休眠模式的作为省电操作模式的媒体驱动器,并且功率 媒体驱动器和主机的消耗可以更加节省。 当处于睡眠模式的CD-ROM驱动器(2)检测到CD-ROM的状态改变(例如插入或弹出)时,它通过使用一个或多个CD-ROM通知个人计算机(1)CD-ROM状态改变 硬件中断信号无轮询。 因此,当CD-ROM驱动器(2)进入/从CD-ROM驱动器(2)进入/从CD-ROM驱动器(2)的状态被CD-ROM驱动器(2)置于睡眠模式时, 当需要驱动时,ROM不需要被驱动或处于正常的操作模式。
