Aero-Bump
Principle #1:
An optical disc having discrete projections (Aero-Bumps™) that are spaced apart in a predetermined pattern on its outer edge, where projections include at least a primary set of projections (BIG) having a first configuration (e.g., height, shape, length, width, size) and at a minimum second set of projections (SMALL) having different height, shape, length, width, size. Our patented Aero-Bumps™ protect the  Data surface (the clear surface of a disc a laser must penetrate to write/retrieve data) of an optical disc by elevating the entire disc uniformly above its storage surface.
NOTE: The location of the second set of projections is specifically chosen to place it between adjacent primary projections to prevent the data surface from contacting the storage surface during extraction or placement of the disc.
Principle #2:
Without lop-siding the disc: (Uneven mass distribution) add protection to a disc by incorporating AERO-BUMPS™ into the design.

Potential Negatives:Where uneven mass distribution might result in accelerated wear and tear, of the bearing sets of a read/write drive, this particularly relevant with high speed drives.
Where uneven mass distribution might result in laser tracking errors particularly relevant in older read/write drives with limited error correction software.

Solution:  Assure that the first and second projections are configured for even mass distribution so as not to lopsided the disc.
Even mass distribution is achieved by:
        -Locating identical primary projection 180 degrees across a radial axis
        -Locating identical secondary projection 180 degrees across a radial axis
        -Maintaining uniform spacing (radial symmetry) of the projections around the entire circumference.
Locating primary and secondary projections at an equal distance from the center of mass of the disc, while maintaining uniform spacing around the entire circumference.
Principle #3:
Maximize the amount of protection to the disc, while allowing the disc to remain compatible to 99% of all applicable read/write drives.
Potential Negatives:
NOTE:  SLOT LOAD DRIVES PRESENT THE GREATEST COMPATIBILITY  CHALLENGES  COMPARED  TO ALL OTHER DRIVE TYPES.
When attempting to Maximize the amount of protection to a disc's data surface through the use of projections, one's greatest concern should be with the potential for incompatibility with the established base of read/write drives particularly slot-load read/write drives.
-In a slot load player/recorder if the primary projections are to tall, wide, long, to close in proximity or lack streamline characteristics, they will most likely become snagged on the dust brush orifice during the loading/ejection process.
-In a slot load player/recorder if the primary projections are to tall, wide, long, to close in proximity or lack streamline characteristics, they will most likely become snagged on the transport roller during the loading/ejection process.
-If at anytime the amount of drag that is created by side profile of the projections exceeds the maximum amount of traction the transport rollers achieve during the loading or ejection processes the disc will become jammed in the player.
NOTE: The disc player depicts a disc using a primary and secondary bump configuration, where the primary Aero-Bump™ is small enough in size and height to allow for normal loading/ejecting in a slot load player/recorder (the most difficult drive to accommodate). The bump configuration depicted in the drawing uses a large enough primary Aero-Bump™ to provide adequate protection to the recording surface while preserving a 99% percent compatibility rating to established base of read/write drives (Tray, Slot, Carousel & Cartridge).


Principle #4:
The first and second projections must not only remain physically compatible to the read/write drives, they must simultaneously maximize their aerodynamics when the disc is spinning, so as not to disrupt the normal recording and play back processes.
-The projections achieve Universally Compatibility to the players, but lack the necessary aerodynamic characteristics to facilitate normal recording and play back processes when the disc is spinning.
-The projections achieve the necessary aerodynamic characteristics to facilitate normal recording and play back processes when the disc is spinning, but lack physical compatibility to the read/write drives.
-An improperly shaped, placed, spaced or orientated projection on the disc will disrupt the normal recording and play back processes by causing vibration when the disc is spinning.
-An improperly shaped, placed, spaced or orientated projection on the disc will increase drag.
Solutions:       
Alternately space at least a first and second set of projections in a precise radial pattern, while orienting their major axis tangent to their centering line. This will allow the alternately spaced projections to remain physically compatible, while simultaneously maximizing the aerodynamic properties of the projections. 
The primary projections: (BIG)
The primary projections must be orientated with it's major axis tangent to the centering line, when the disc is spinning the alignment of the primary projections major axis tangent to the centering line, is critical in maximizing the efficiency of the aerodynamic shape:
The secondary projections: (SMALL)
If applicable, the secondary projections are oriented with its major axis tangent to the centering line, when the disc is spinning the alignment of the primary projection's major axis tangent to the centering line, is critical in maximizing the efficiency of the aerodynamic shape: (in case the secondary projections are circular, IE: no major axis)
NOTE:  The second set of projections does not have to be spherical it can be any shape so long as it is smaller to the primary projections and it maximizes aerodynamics while minimizing the side profile in relation to slot load read/write drives. (In this case the secondary projections are circular)
Where height, shape, orientation and location of first projections are chosen to maximize protection of disc surface by creating the SAFETY-GAP™, the size, shape and location of the second set of projections chosen to:
-Minimize overall interference with drives (particularly slot load drives) without sacrificing the safety of the disc.
-Allow for greater spacing of the primary projections, ultimately reducing the total number needed to provide adequate protection.  By allowing for greater spacing of the primary (larger) projections fewer can be used per disc without sacrificing safety, it is advantages to use fewer primary projections because it increases the compatibly to slot load drives.
-Be placed between adjacent primary projections to prevent the data surface from contacting the storage surface during extraction or placement of the disc.
Principle #5:
The projections must not only remain physically compatible while simultaneously maximize their aerodynamics when the disc is spinning, they must take into consideration weight distribution and the sandpaper effect.
Potential Negatives:
If a projection is designed with a pointy tip (small or sharp) the distribution of the disc's mass (weight distribution) will be concentrated in a very small area,  increasing the possibility of the bump damaging the disc below it if discs are stacked one on top of another (spindle packs).
Projections with a small or sharp (pointy) contact point, will quickly shorten in height do to the sandpaper effect (The inevitable gradual wearing down of the bumps resulting from physical contact with varying storage surfaces) the relatively small surface area is unable to withstand erosion.
Solution:
Projections are shaped to provide enlarged contact surface (flat contact point) area that reduces the weight per distributed area, yet the altered shape preserves the favorable aerodynamic properties of the original shape or design projections that are aerodynamically shaped with approximately the bottom 1/5 "removed  to create a flat surface at the contact point:
