I hv been hearing that a dvd player and a DVD ROM differ in their operation of reading a disk....A DVD Rom uses the famous laser technology ..Then how,does the DVD player operate?
This my own understanding: Correct me if I am wrong:
If you are talking about DVD player, that connects to your TV to play DVD movies and DVD ROM that hooks up in your computer to read DVD/CD datas and then they're little bit different.
DVD Players (the one that hooks up to your TV) is specifically design to read DVD Files (such as DVD Movies) and most of them can read cd files (music). It depend of what the DVD firmware (the software in the DVD player) can read.
DVD ROM (that one that hooks up in the computer) Unlike the DVD player, it can read a wide variety of data files. From movies to .exe files etc.... But the problem is, it only reads them. For example, your are going to watch DVD movies on your computer through your DVD ROM, you will need another program in your computer to play it, such as DVD decoder or something that plays dvd files. If you don't have a dvd decoder, you cannot watch the movies. But it still be able to displays the files in the DVD disk.
Most games now adays are now on DVD disk, since it won't fits in a regular CD. And these DVD Game disc are can only be use in computer with the DVD ROM. You will not be able to display the files (.exe etc...) if you insert the disc to your DVD player. It will only say Disc error or something.
DVD player is design for DVD movies and probably music and pictures. It only reads files that software in dvd player is program to read.
DVD ROM in the computer can read a wide variety of files but sometimes you will a different program, especially DVD movies to play them to your computer.
I hope this is not confusing. hehehehe
And by the way, they both use laser to read into the disc
