<p>A spindle assembly is provided for rotatably supporting and driving a video information disc in a video recorder-playback machine. The spindle assembly comprises a vertically extending journal having a generally truncated conical shape and supported for rotation in an inverted position within a complementary shaped spindle housing. Pressurized air is supplied through a plurality of slotted flow paths to the support interface between the journal and the spindle housing for supporting the journal for relatively high speed rotation on a cushion of air.</p> |
