Audio Cd Pits Simulation

Audio Compact Disc Player

In a compact disc player, a laser beam must track a spiral row of pits which are 0.5 micrometers wide with track spacing 1.6 micrometers. Tracking is aided by a three-beam laser arrangement. In addition to staying on the track, which is much narrower than the 100 micrometer groove separation on a vinyl record, the rotation speed must be adjusted as the beam tracks inward or …

The game cannot play the CD audio at the same time it is reading the track data from the CD. This can be solved by using a larger install. There is also a relatively common problem with Windows 95 when there is more than one CD-ROM drive installed (for example a CD-ROM drive and a DVD-ROM or burner).

By means of a laser diode and a complex optical system a light signal with λ ≈ 500 nm is focused on the bottom side of the CD.The light is reflected back by pits and lands with a phase difference. The land and pit vertical height is accurately sized so that the signal reflected by the land has a phase difference of 180° with respect to the incoming wave.

CD and DVD for the students to compare with their macro-scale data. CDs and DVDs as Diffraction Gratings {CDs/DVDs display streaks of colors when white light falls on them {The digital information (alternating pits and smooth reflecting surfaces) stored on the discs form closely spaced rows acting like a reflecting diffraction grating

COMPACT DISK STANDARDS & SPECIFICATIONS

COMPACT DISK - DIGITAL AUDIO (CD-DA): • The CD-DA was developed jointly by N.V.Philips and the Sony Corporation for storing audio data. • CDs have a diameter of 12cm, and are played at a Constant Linear Velocity (CLV). • Information is stored in such a way that the length of the pits is always a multiple of 0.3um. A change from pit to ...

OPTICAL CD CODE. This page is about how a common optical medium: the CD, is read (the 120 mm Compact Disc - Digital Audio, Red Book CD from 1982, by Philips & Sony). This page doesn't show you all there is to say about the CD, but it should make clear how to read the code on it. Inside a CD is a flat light reflecting layer called "land".
