Playback is accomplished with the laser alone : taking advantage of the Faraday effect, the player senses the polarisation of the reflected light and thus interprets a 1 or a 0.

Electromagnetic radiation had been first linked to electromagnetism in 1845, when Michael Faraday noticed that the polarization of light traveling through a transparent material responded to a magnetic field ( see Faraday effect ).
33.
The operation of [ some of ] the devices depends on the Faraday effect ( which in turn is produced by magneto-optic effect ), which is used in the main component, the Faraday rotator.
34.
Rotation of light's plane of polarization may also occur through the Faraday effect which involves a static magnetic field, however this is a distinct phenomenon that is not usually classified under " optical activity ."
35.
YIG has a high Verdet constant which results in the Faraday effect, high Q factor in microwave frequencies, low absorption of infrared wavelengths down to 1200 nm, and very small linewidth in electron spin resonance.
36.
The Faraday effect is caused by left and right circularly polarized waves propagating at slightly different speeds, a property known as phase shift, induced by the Faraday effect, is to rotate the orientation of a wave's linear polarization.

The Faraday effect can, however, be observed and measured in a Terbium-doped glass with Verdet constant as low as ( H " " 20 rad T " 1 m " 1 ) ( for 632 nm light ).
39.
The highest Verdet constants are found in terbium doped dense flint glasses or in crystals of TGG . The Faraday effect is chromatic ( i . e . it depends on wavelength ) and therefore the Verdet constant is quite a strong function of wavelength.
40.
Being a spatial dispersion effect, the induced optical activity exhibit different behavior under the operation of wave vector reversal, when compared with the Faraday effect : the optical activity increment associated with the electrogyration effect changes its sign under that operation, contrary to the Faraday effect.
