摘要： A method of determining whether a defect exists on an information storage medium is provided along with a recording/reproducing apparatus using the same. Such a method comprises: seeking a defect entry whose state information indicates that a defect block or a replacement block has been re-initialized without certification from a defect list for managing an information storage medium and including state information of the defect block and state information of the replacement block, wherein the medium includes a spare area for recording the replacement block to replace the defect block occurring in a user data area on the medium; and certifying the defect block or the replacement block registered in the sought defect entry. As a result, defect information can be effectively rearranged for quick re-initialization without certification in order to improve the performance of a drive system.

摘要： A storage device performs error correction for all data read from media. Correctly read data or data that is corrected following the reading is transferred to a host for use. If the error correction fails, the storage device transfers a unique error code. The host distinguishes the received data between normal one and unique one. The normal data flows into main data handling routine and the unique code flows into error data handling routine. The processed results of both data are stored into system memory area in the host. The host controls the read out schedule and response to the unique code. This method can prevent the host breakdown from data trouble in the external storage device.
摘要翻译：存储设备对从介质读取的所有数据执行错误校正。正确读取读取后校正的数据或数据被传送到主机以供使用。如果纠错失败，存储设备将传输唯一的错误代码。主机将接收到的数据区分在正常的和唯一的数据之间。正常数据流入主数据处理程序，唯一代码流入错误数据处理程序。两个数据的处理结果存储在主机的系统内存区域中。主机控制读出的时间表和对唯一代码的响应。该方法可以防止主机从外部存储设备中的数据故障中排除故障。
