Self-adapting flow restrictors

摘要

A record storage apparatus consisting of a stack of co-rotating spaced apart flexible record storage disks are stabilized by circumferentially uniform radially outwardly flowing air under a quiescent operating condition. The record storage disks are normally in a parallel relationship. To form a transducing access opening, the disks are axially partially moved to create an enlarged interstice between two of the record storage disks for enabling a transducer to reach a recording surface on one of the two record storage disks. Disks adjacent to such access openings come closer together but should not touch. To avoid the touching and maintain stability, air flow between such more closely spaced disks is automatically adjusted as the disks approach each other.
