Abstract:
1. A high-capacity pick-up mechanism operable for selectively reading data from and/or writing data to one or more surfaces of one or more optical storage media, the pick-up mechanism comprising: a first pivotable structure having a first end and a second end, wherein the first end of the first pivotable structure is located remotely from the second end of the first pivotable structure, and wherein the second end of the first pivotable structure is positioned adjacent to and in a spaced-apart relationship with a top surface of a first optical storage medium; a second pivotable structure having a first end and a second end, wherein the first end of the second pivotable structure is located remotely from the second end of the second pivotable structure, and wherein the second end of the second pivotable structure is positioned adjacent to and in a spaced-apart relationship with a bottom surface of the first optical storage medium; a first reflective element associated with the second end of the first pivotable structure, wherein the first reflective element is operable for transmitting light to and/or receiving light from the top surface of the first optical storage medium; a second reflective element associated with the second end of the second pivotable structure, wherein the second reflective element is operable for transmitting light to and/or receiving light from the bottom surface of the first optical storage medium; a light source associated with both the first end of the first pivotable structure and the first end of the second pivotable structure, wherein the light source is operable for transmitting light to the first reflective element along a first optical path, and wherein the light source is operable for transmitting light to the second reflective element along a second optical path; and a light receiving device associated with both the first end of the first pivotable structure and the first end of the second pivotable structure, wherein the light receiving device is operable for receiving light from the first reflective element along the first optical path, and wherein the light receiving device is operable for receiving light from the second reflective element along the second optical path.
