    • A storage device includes an access counter that counts the number of track changes or the number of accessed sectors in accessing the recording medium, an access judgment unit that judges whether the recording medium is accessed successively by a host, a count judgment unit that judges whether the count counted by the access counter has reached a predefined number of times when the access judgment unit judges that the recording medium is accessed successively, and an access delay unit. The access delay unit delays the access to the recording medium so that a transfer rate between the storage device and the host is adjusted to a predefined transfer rate when the count judgment unit judges that the number of the count has reached the predefined number of times.
    • 存储装置包括访问计数器,其对访问记录介质的轨道变化次数或访问扇区数进行计数;访问判断单元,判断记录介质是否被主机连续访问;计数判断单元,判断是否 由访问计数器计数的计数器已经达到预定次数,当访问判断单元判断连续访问记录介质时,访问延迟单元。 访问延迟单元延迟对记录介质的访问,使得当计数判断单元判断计数的数量已经达到预定次数时,存储设备和主机之间的传送速率被调整到预定的传送速率。
