Diverter means for flexible disk pack and associated method

An improved partitionable disk recording subsystem including:

• a disk pack comprising a stack of flexible recording disks adapted to be co-rotated and to be partitioned, "end-wise"--that is normal to major disk surfaces--by thrust means projected into the pack, and not "from the side"--that is, not from the direction of a disk edge;--the thrust means being adapted to cooperate with disk structure and comprising further means which preclude impeding of said disk pack structure during rotation thereof;
• the disk stack being arranged to generate at least one prescribed partition gap, each such gap exposing, at least partially, a respective disk recording surface for transducer operation;
• and
• transducer assembly means adapted to be selectably projected into a selected one of said gaps, with the gap being maintained, partitioningly, while this assembly means presents at least one transducer-head means into transducing relation with the associated disk recording surface;
• said assembly means including transducer actuator means adapted to selectively reciprocate said transducer head means into, and out of, said associated gap;
• as well as being operatively associated with at least one diverter means adapted to make initial entry into said partition gap and to maintain this gap during rotation of the pack, while shielding an associated transducer-head means protectingly.
