In this article I will be showing you four little known tips to fix scratched CD or DVD and recover the data within, Every user has had trouble with a scratched CD or DVD. The theory goes like this – A CD/DVD reader or player uses a laser beam to read the data on the disk. This laser beam crosses the protective plastic layer and reads the real recording metal layer. If the protective plastic layer is scratched, the laser will be unable to pass resulting in non-readable disc. In the case of data CDs the CD/DVD reader is unable to read the CD/DVD properly resulting in reading errors while in case of audio/video discs, the CD player skips when we play it.

If somehow we manage to re-smooth this protective layer then the laser will reach the data and read it, now there are many ways we can achieve this using common household item’s as discussed below:

1). Toothpaste – Yups! Toothpaste is our very first scratched CD/DVD fixer, you can use any non-gel based toothpaste for this, just put a very small amount of it on the scratched area and polish it gently using a cotton swab, sometimes the paste may cause new minor scratches but they are just superficial. Now just wash the cd using water.

2). If the above trick does not work try some metal polish like Brasso gently wiping with a soft cotton ball followed by application of Vaseline.

3). Baking Soda – make a small quantity of baking soda paste and apply using a soft cotton cloth buffing the bad scratch. Clean the baking soda before using the disc.

4). You can also try using some oil as a polishing agent this also works many times.

There are many daily use products that can be used to get the cd working just keep on experimenting, please note that you must take special care while using the above tips as

Choosing an MP3 player used to be a much easier shopping decision than it is today. Just a couple of years ago, only MP3 players played MP3 music. Nowadays, every man and his dog that has a mobile phone, laptop or memory storage device can play MP3 music. Now that there are a few more things to take into consideration, it is wise to think about a few issues before splashing out some serious money (or trying to save some serious money).

Part I – Do you need an MP3 player?

Probably the most important question you need to ask yourself. Why do you want one? Does your mobile phone already come with an MP3 player? What about your laptop? Why would you need one if you’ve already got one? The only reason MP3 players exist in their own right is because a mobile phone is a much better device for making phone calls on the go, and an MP3 player, well, it is a much better device for playing MP3 music. When there is a comprise in function, there is a comprise in function (i.e. quality and performance).

Part II – Do you need a good MP3 player?

Probably the second most important question you need to ask yourself. It does sound like a rhetorical question. Of course you want a good MP3 player, but please provide a definition for “good”. Do you want something that looks good, plays good (well is probably a better word) or sounds good (or all three perhaps). Remember that these days people will buy things for the image (looks/sounds good), performance (plays good) and quality (lasts good). All three come at a cost (though not necessarily equal in weighting), and usually you’ll find that two out of three ain’t bad. Sometimes big name brands not only looks good (the Japanese designers are experts at this), sounds good (for example, hey look, I’ve got a Sony -insert model here- !), but they might actually have good performance or quality as well (Some say the iPod belongs in that category, but I don’t want to start another online forum about it). But most of the time, practical people start with performance or quality, and just hope that it’s something they can hide in their designer label clothing’s MP3 pocket.

Despite how great CDs are, many people still prefer audiocassettes to them, especially when it comes to listening to audio books.

Below are some of the reasons why:

One, Audio books in a CD format cannot contain more than 75 minutes of content but audiocassettes can hold as much as 90 whole minutes (and, in many cases much more) of narration.

I agree you can have the entire audio book spread out in several CDs, but not many people like to carry around too many CDs.

So, while you might need just a few audiocassettes for a particular audio book, you will probably need many more CDs for that same audio book.

Two, most people don’t like to spend extra cash buying CD audio books when they can get the same audio book cheaper in audiocassettes.

For example, while an unabridged version of “Harry Potter and the Goblet of Fire” on 12 audiotapes can be bought for just $31.96 on the Barnes & Noble website, the CD format from Barnes & Noble costs almost double that amount – exactly $55.96 for 17 sets of CDs!

Of course, its not that they want to rip you off – it’s simply because it costs much more to produce CDs than it does to produce audiocassettes.

Three, when you turn off your CD player while listening to an audio book, you won’t be able to resume from the particular spot you left off. With a cassette, you can begin from the exact same spot you left off.

With CDs it can be frustrating when driving because each time you turn off your car, it would mean restarting the audio book or trying to locate exactly where you stopped.

Of course there are modern and more advanced CD players that can now save your location when you turn off your car, thereby allowing you to resume at the exact same spot you left off.

This won’t work when you turn off the car AND take out the CD. But it will work with an audiocassette!

Four, because audio books are mainly just narration, many users don’t see why they should spend the extra money to buy CDs because of issues of recording quality when they can get near enough the same quality with audiocassettes.

Their argument is that if it was sound “quality” they wanted, they would go for audio books in CD formats, but sound quality is the same with audiocassettes and CDs when it comes to audio books.

In more succinct terms – “the voice of humans (without drums and other musical paraphernalia) has very little to gain from the depth and clarity that comes with digital recordings in CD format!
