    • PURPOSE: To overcome a problem such that AV data and information for managing AV data recorded on the disc medium of a video recorder/reproducer may possibly be destructed when an apparatus for supporting a low level access command is connected with a video audio recorder/reproducer. CONSTITUTION: The recorder/reproducer comprises a circuit 11 for controlling recording/reproduction to/from the AV data recording region of a recording medium, an I/O circuit 9 for receiving both kinds of low level access command and non-low level access command; and means for identifying the source unit of command which certifies the source of command, determines whether a received command is a low level access command or a non-low level access command, and further determines whether the source of command is certified or not in case of a low level access command. At least when a write command is received, the recording/reproduction control circuit 11 determines whether a write command is executed or not, based on the identification results from the means for identifying the source unit of command.
    • 目的:为了克服当用于支持低级别访问命令的设备与视频录音机/再现器连接时,用于管理记录在录像机/再现器的盘介质上的AV数据的AV数据和信息可能被破坏的问题 。 构成:记录器/再现器包括用于控制从记录介质的AV数据记录区域的记录/再现的电路11,用于接收两种低级别访问命令和非低级访问命令的I / O电路9 ; 以及用于识别证明命令源的命令的源单元,确定接收到的命令是低级别访问命令还是非低级访问命令的装置,并且进一步确定命令源是否被认证,在这种情况下 的低级访问命令。 至少当接收到写命令时,记录/再现控制电路11基于来自用于识别命令的源单元的装置的识别结果来确定是否执行写入命令。
