    摘要： In a data storage device, a head writes data so as to protect data from off track writing to adjust tracks. A control unit acquires large ring buffer during sequential writing and performs a retry to return adjacent tracks, according to data of a return sector area of the ring buffer when a write error occurs. A write error due to a detection mistake of an off track error can be prevented.

    摘要翻译： 在数据存储装置中，头部写入数据以保护数据不被偏离轨迹写入以调整轨迹。 控制单元在顺序写入期间获取大环形缓冲器，并且当发生写入错误时，根据环形缓冲器的返回扇区区域的数据执行重试以返回相邻轨道。 可以防止由于偏离磁道错误的检测错误而导致的写入错误。

    摘要： 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.
