RHD-CARD TRANSPORTATION AND POSITIONING

摘要

A rotating drum contains a plurality of read/write heads rotating therewith. A cartridge, having first and second sections, is positioned in a fixed position relative to said drum and has a plurality of cards retained in said first section with means for selectively releasing any card. A first chute is positioned to transport any card from the cartridge to a predetermined and non-rotating position around said drum, where the read/write function occurs. A second chute is positioned to transport a card from its predetermined position around the drum back to the second section of the cartridge, which section is maintained free of cards except for the returning card. Means are provided for maintaining an air bearing between the card and the drum during transport of the card, as well as when the card is in its predetermined position around the drum periphery.
