Abstract
A latching mechanism for an optical disc system using an optical disc mounted in a disc carrier, the disc carrier and disc housed within a protective cartridge. A spring biased rotary cam in the disc drive includes an eccentric pin at its outer end which engages a spring biased catch member on the disc carrier during insertion of the cartridge. The cam has a cam groove formed in its outer surface having alternating spiral and axial segments. During the initial insertion of the cartridge, the rotary cam rotates as it is driven axially by the disc carrier causing the eccentric pin to move the catch member laterally. This disengages the catch member from the cartridge and places a second projection on the catch member in line with a laterally projecting lip within the disc drive. When the cartridge is retracted, the rotary cam moves axially until the second projection and lip contact so further movement of the cartridge leaves the disc carrier within the disc drive. During reinsertion of the empty cartridge, the rotary cam moves axially and rotates to move the catch member laterally so it becomes offset from the lip and reengages the cartridge. Withdrawal of the cartridge and disc carrier proceeds with the rotary cam moving axially along the other axial cam groove segment.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
