(5) Spindle automatic stop mode
Normally, with the cartridge loaded, the spindle rotation is maintained until the spindle is
instructed to stop by the START/STOP UNIT command. The spindle auto stop function
automatically stops the spindle after the command has not been issued from the host for about 30
minutes (default value). When the command is issued from the host with the spindle
automatically stopped, the optical disk derive turns the spindle again and performs processing in
the same manner as in a ready state without posting a not ready state.
The access supervision time from the host is about 33 minutes as the default. However, it can be
changed by the MODE SELECT command.
The spindle auto stop mode can also be changed by the MODE SELECT command.
Table 4.5 shows spindle auto stop mode setting.
