sound recording device.

esp. high-resolution audio-visual material.

center. The form of the groove tells us what movie is playing. This is called the Media Identification Data, or MID.

WHY WAS THE DVD INVENTED?

~ The DVD was invented for easier usage of recording and showing media. It was invented to hold more information than the VHS.

IS THERE A FUTURE FOR THESE MEDIA RECORDERS?

Personally, I don’t think there is a future for the cassette and VHS. You don’t

really see much now-a-days, except for films in science, history, and other subjects

that require a lot of information. The DVD, however, has changed a lot since it first

was invented. For example, we now have Blu-Ray disks that are supposedly better

than the first DVDs. I really haven’t seen a movie on Blu-Ray but I’m guessing it’s the

exact same. If it’s not, oh well. This is just my opinion. And everyone is entitled to

their own. I don’t think anything is going to change within the next 10 years.
