ABSTRACT:
For producing a transducer access opening in a stack of rotating flexible magnetic record disks, a co-rotating part axially deflects the peripheral edges of selected disks for partially axially separating same. The co-rotating part may take the form of a thin disk, several thin disks, or shaped as a roll. The axis of the roll is obliquely inclined against the disk pack rotational axis. The roll has a resilient surface such that, after the roll has been inserted into the disk pack, the flexible disks move up the outer surface of the roll to be deflected.
