Abstract
According to the present invention, in a drive interface provided between a drive device for writing information in a recording medium or reading information from a recording medium and a controller device for controlling the drive device, there are provided a data signal line for transmitting data signals between the controller device and the drive device and mode signal lines for transmitting mode signals for identifying the kinds of data to be transmitted by the data signal line, and the kinds of data to be transmitted are identified by decoding the mode signals. Write operation and read operation of the drive device are also controlled by the mode signals.
Claims11
A drive interface provided between a drive device for writing information on a recording medium or reading information from the recording medium and a controller device for controlling the drive device, said drive interface comprising:
- a single bidirectional data signal channel for transmitting a plurality of kinds of data signals bidirectionally between the controller device and the drive device;
- and
- mode signal lines, distinct from said data signal channel, for transmitting mode signals from the controller device to the drive device for identifying kinds of data transmitted by said data signal channel.
A drive device, connectable to a controller device for controlling said device, for writing information on a recording medium or reading information from the recording medium, said drive device comprising:
- a single bidirectional data signal channel for transmitting a plurality of kinds of data signals bidirectionally between the controller device and said drive device;
- mode signal lines, distinct from said data signal channel, for receiving mode signals from the controller device for identifying the kinds of data transmitted by said data signal channel from the controller device;
- and
- control means for controlling write operation or read operation of said drive device on the basis of the data signals received by said data signal channel and the mode signals received by said mode signal lines.
A drive device, connectable to a controller device for controlling said drive device, for writing information on a recording medium or reading information from the recording medium, said drive device comprising:
- a single bidirectional data signal channel for transmitting a plurality of kinds of data signals bidirectionally between the controller device and said drive device;
- mode signal lines, distinct from said data signal channel, for receiving mode signals from the controller device for identifying the kinds of data transmitted by said data signal channel;
- and
- means for identifying the kinds of data transmitted by said data signal channel, by decoding the mode signals received on said mode signal lines.
