1) Plastic (Polymer) Optical Fiber is used to transmit signals down a flexible, plastic material. 2) Polycarbonate coatings are used on optical discs to prevent scratching the underlying surface that has the actual pits and lands.
Magnets are or rather were used to record audio or video on cassettes media earlier (which had/have magnetic tape in them on which data was recorded using magnet), which have now (still used) but taken over by optical media (CDs, DVDs, Blurays). Hard Disks/Drives in computer also use magnets to record on them.

Optical receptors are complex apparatus used in the detection of tumors or HIV, for instance. There are even optical receptors that are used in the process of aging Scotch whiskey. Laboratories and hospitals would be the place to find optical receptors, but equipment like this is not sold to the public.
It can be used for this purpose, but the quality may not be great. However, some concerts do not allow the use of recording equipment. Make sure you check this out or you may find yourself getting kicked out.
The U.S. magnetic and optical recording media industry employed 20,869 people in 1997
In 2000, the U.S. magnetic and optical recording media industry employed over 36,000 people. This number has since declined due to changes in technology and consumer preferences.
In us, our eyes. In man made items they are used in such things as cameras, phones or other optical equipment
