    • Data difficult to be written to a target sector (write) of a hard disk is recorded to a MRAM. The target sector (write) to which the write has been difficult is checked in a background of performing data write to the next target sector (write). When there is no error, the data stored in the MRAM is written to the target sector (write) of the hard disk. When there is any error, the data stored in the MRAM is written to an alternative sector of the hard disk. Data difficult to be read from a target sector (read) of the hard disk is recorded to the MRAM. The target sector (read) from which the read has been difficult is checked in a background of performing data read from the next target sector (read). When there is any error, the data stored in the MRAM is written to an alternative sector of the hard disk.

    • The signal output device of the present invention comprises of a driver circuit and a controller. The signal sending method of the present invention sets any one of a plurality of the different sending rates. The method also includes setting a slew rate of the driver circuit to a standard value that is in accordance with the predetermined data transfer rate, thereby starting signal transmission. The next step involves determining whether or not a data transfer error occurrence rate is below a predetermined allowable threshold. Then, changes in the slew rate of the driver circuit are made if the data transfer error occurrence rate is determined to be over the allowable threshold. Next, a search for a slew rate value that can decrease the data transfer error occurrence rate below the allowable threshold or decrease the data transfer error occurrence rate is performed. The new slew rate value is set as a new standard value. Finally, the process ends by setting the new standard slew rate for the driver circuit if the slew rate value can decrease the data transfer error occurrence rate below the allowable threshold or decrease the data transfer error occurrence rate.
    • 本发明的信号输出装置包括驱动电路和控制器。 本发明的信号发送方法设定多个不同的发送速率中的任何一个。 该方法还包括将驱动器电路的转换速率设置为与预定数据传输速率相一致的标准值,从而开始信号传输。 下一步涉及确定数据传输错误发生率是否低于预定的允许阈值。 然后,如果确定数据传输错误发生率超过允许阈值,则驱动电路的转换速率的变化。 接下来,执行可以将数据传输错误发生率降低到允许阈值以下或者减少数据传输错误发生率的压摆率值的搜索。 新的压摆率值被设置为新的标准值。 最后,如果转换速率值可以将数据传输错误发生率降低到允许阈值以下,或者减少数据传输错误发生率,则设置驱动电路的新标准转换速率结束。
