Temperature and pressure stabilizer systems for random access disc memory systems

Claim 1

IN A MAGNETIC STORAGE SYSTEM, AT LEAST TWO PARALLEL RECORDING DISCS ROTATABLY MOUNTED ON A SUPPORT FOR ROTATION IN A SELECTED SENSE, AN IMPERFORATE CYLINDRICAL SURFACE JOINING THE DISC AT AN INTERMEDIATE RADIUS ON EACH DISC, SAID DISCS HAVING CONFRONTING IMPERFORATE RECORDING AREAS EXTENDING OUTWARDLY FROM SAID SURFACE, AN ARM EXTENDING RADIALLY BETWEEN SAID DISCS, TRANSDUCER MEANS MOUNTED ON SAID ARM FOR READING SAID WRITING INFORMATION ON SAID RECORDING AREAS, AND AN AIR BARRIER ADJACENT TO AND BEHIND SAID TRANSDUCER MEANS IN THE SENSE OF ROTATION OF SAID DISCS, SAID BARRIER BEING SPACED FROM AND EXTENDING BETWEEN SAID DISCS INTO PROXIMITY WITH SAID MEMBER, WHEREBY A STREAM OF AIR FOR MAINTAINING STABLE TEMPERATURE DISTRIBUTION IN SAID SYSTEM IS PRODUCED ENTERING BETWEEN SAID DISCS IN A REGION AHEAD OF SAID TRANSDUCER AND EMERGING IN A REGION BEHIND SAID BARRIER IN THE SENSE OF ROTATION OF SAID DISCS, AND SAID TRANSDUCER MEANS IS PROTECTED FROM AERODYNAMIC BUFFETING.
