SCSI磁带驱动器还会导出sr_init_command，以将请求转换成SCSI CD - ROM读或写请求。
The SCSI tape driver also exports an sr_init_command that turns a request into a SCSI CD-ROM read or write request.
例如，一个15,000RPM驱动器的读操作需要大约3.5毫秒的平均寻道时间，写操作则需要大约4毫秒。
For example, a 15,000 RPM drive has an average seek time of approximately 3.5 milliseconds for reads and 4 milliseconds for writes.
也，最大多数的激光唱碟和当磁盘片不能够被读的时候数字化视频光盘驱动器被设计戴面具或跳越数据，一些将会尝试到再读数据，但是最后地将会跳越或戴面具如果后来的阅读不及格。
Also, most CD and DVD players are designed to mask or skip data when the disk cannot be read, some will attempt to re-read the data, but ultimately will skip or mask if subsequent reads fail.
该系统由读表仪、信号驱动器、数据传输系统、数据传输软件、工艺辅助生成软件组成，具有数据记录、数据传输、工艺数据辅助生成等功能。
The system consists of instrument of data input and module of signal adjustment and transformation, and has many functions, such as keeping data transforming data, and generating process data.
