Abstract
In an information disk drive system, a pivoted shutter opening lever is positioned in a cartridge receiving guide in the same plane as the disk in the cartridge. The lever is mounted on a movable pivot with a shutter engaging member positioned to begin opening the cartridge shutter to expose a segment of disk recording tracks only after the segment is inside the disk drive and to complete opening of the shutter at an intermediate stage of cartridge insertion to allow nesting of disk access components within the disk access opening in the cartridge prior to the cartridge reaching its final operating position. Interference between the opening lever and the fully opened shutter during final travel of the cartridge is avoided by a mechanism which moves the lever pivot by a sufficient amount to allow the shutter engaging member to translate in a straight line parallel to the insertion path of the cartridge during final insertion motion of the cartridge. Two embodiments of the pivot moving mechanism are shown.
