Data CDs, on the other hand, hold anything. Theyâre just another media on which you can store files from your computer. The format of a data CD is even similar to the format of your computerâs hard disk. It has a file system, directories, folders and files. But your car stereo knows nothing about file systems, folders and the like. All it knows is how to stream that raw audio data off of an audio format CD.

Throw distance x width of screen in inches = distance from screen to projector lens. Throw distance is the distance from the screen to the projector. For example, if your screen is 87â wide and the throw distance of your projector is 1.3, the projector should be 113â (87x1.3=113â) from the screen. Remember to measure from the center of the projectorâs lens straight to the screen, like the above image shows. For most people, your projector will list a throw distance, or throw ratio in this case, of something like 1.5-2.25. The wider the throw ratio, the more wiggle room you have in placing your projector.
