In front of the loud speaker was the revolving disk of a phonograph record.

Actually, he had talked with a revolving disk.

The sunlight glinted and sparkled from the polished metal surfaces of the slowly revolving, three-hundred-yard-diameter disk.

Not until he reached the passenger lounge, on the outer skin of the great revolving disk, had he acquired enough weight to move around almost normally.

I was in the centre of a revolving disk which was whirling so fast that nothing could stay put.

Silence followed, except for the slow whirr of the revolving disk.

Embedded deep in the revolving disk may even be a newborn planet.

As they watched, a section of the revolving disk lit up as though a giant flashbulb had gone off inside.

Other kinds of skimmers have revolving disks, like farmers' harrows, to which oil adheres and is then removed by wipers.

Radio and X-ray observations also revealed sudden flares streaking out in opposite directions from the revolving disk.
