Abstract

Disclosed is a magnetic imaging system including a stationary drum 2 coated with a magnetic recording media on which latent magnetographic images are to be recorded and a rotating annulus 4 having a plurality of multiplexed recording heads 6 evenly spaced about its periphery. As shown in Figure 1, the rotating annulus moves from its rest position at one end of the stationary drum to the other end of the drum to record images on the drum surface. After the annulus has returned to the rest position, a transfer station consisting of a crolyn tape 8 and a flash illuminator assembly 10 is brought into proximity with the stationary drum as shown in Figure 2. With the tape in contact with one of the images stored on the drum, the illuminator is flashed to effect thermoremanent transfer of that image to the tape.

MAGNETIC MASTER IMAGING DRUM SYSTEM (Cont'd)

The tape can be indexed by a control/drive system 12 to store many sequential images followed by rewinding of the tape into its module which is removed and taken to a printing engine. A second transfer station can record a second tape module to permit duplex and print-while-rewind capabilities by the printing engine.
