Dubbed "Compact Memory Disc Adapter and Methods of Use Thereof," the patent filing made in May of 2006 and published for the first time on Thursday explains that conventional rotating memory storage discs such as CDs and DVDs are currently produced in standard 12 cm and reduced diameter 8 cm configurations.
Software is traditionally shipped on the 12 cm discs, but many applications exist today that require less storage capacity than what is available on the those discs, the filing adds. However, slot-loading drives found in notebooks and car audio systems are only designed only to accept 12 cm discs.
"In such situations it would be advantageous to use a reduced diameter (lower storage capacity) disc," Fadell explained. "Such advantages include reduced shipping costs, reduced production costs, etc."
The iPod chief pointed out that one currently available solution to using reduced diameter discs in slot drives is that of a rigid adapter that when used in conjunction with the reduced diameter disc enables a disc player to accept and play the reduced diameter disc.
"However, this solution does nothing to reduce shipping costs since the rigid adapter (with its larger footprint) must be shipped with the reduced diameter disc and therefore a standard sized shipping container must be used to accommodate both the rigid adapter and reduced diameter disc," he wrote. "What is needes is a cost effective method and apparatus for shipping reduced diameter discs that assures the end user will be able to use the reduced diameter disc in a slot drive designed exclusively for a standard diameter disc."
Therefore, Fadell's invention calls for a "compactable memory disc adapter" that can be shipped in a compact form and expanded by the customer once extracted from the retail packaging. It could then be fitted around the edges of a 8cm mini-disc, effectively allowing for the reduced diameter disc to play in a slot interface designed exclusively for standard 12cm diameter discs.
Such an adapter can exist in more than one form, the iPod chief goes on to explain. One method includes two separated portions that are mated together via a locking mechanism to form the expanded adapter.
"For example, such a locking mechanism can include tabs that when mated with corresponding tab receivers form the expanded memory disc adapter," he explained. "Again it should be noted that such an embodiment could be implemented with any number of portions and corresponding locking mechanisms along the lines described above. It should be noted that when in a compacted configuration the portions are stacked one atop the other in such a way as to have a reduced footprint."
Another method for construction of the disc adapter could include portions that are coupled via foldable joints. Under this method, the portions are folded apart in an unfolding operation using the foldable joints.
