  • Disk playback device and method of terminating playback of disk
    Patent number: 6104678

When at least a predetermined quantity of data remains in the memory, signaling sound generating means produces a signaling sound three times and a display portion is caused to flash. On the other hand, if the quantity of data remaining in the memory is not greater than a predetermined amount, the sound generating means produces a prolonged signaling sound once and causes the display portion to flash. The display operation is terminated if no disk change is made within a specified period of time thereafter.
