Compact Disks

1 If someone says to you your music CDs don&39;t really hold any music on them, and they only have numbers recorded on them, you may not believe it. In fact, he is right in that sound is actually recored onto the CDs as special numbers --a digital code. The code is pressed onto the CD as bumps on a long spiral track almost five kilometers long. These bumps are an average of 0.5 microns wide.

2 A small laser beam shines onto the bumps as the CD turns. The light is reflected back to a receiver that records how the laser light bounces back. This lets the CD player turn the reflected light back into the original code. This means you can hear the original code as music.

3 Digital codes are used with many technologies. E-mail needs these kinds of code numbers. Space probes communicate with their ground station on earth using digital codes. Bar codes are read as digital codes in computer systems. Digital communications with cell phones need digital codes. Weather radios also tune in to specific signals using these codes.

4 There are many types of compact disks. One format is called CD-RWs. They can be&39; recorded on and re-recorded on (rewritten on) as you would do with a floppy disk. Another format is the CD-ROM. The technology for recording on these disks is different from other CDs. These CDs have a dye layer that the CD writer can darken or leave clear. The clear and dark spots are the digital code. CD-ROM stands for Compact Disc -- Read Only Memory. This disk is like a "super" floppy disk that can hold lots of information. One CD-ROM can h01d the same amount of data as 500 floppy disks. Information is permanently recorded onto it. Computer games and other programs are considered to be CD-ROMs.

5 CDs were first sold to the public in 1982, These CDs still play. well and sound fine. Current CDs are expected to last between 70 to 200 years. Of course, you can make sure your CDs last a long time by taking care of them.

6 Science keeps on developing. It may not be many more years before a completely new technology is invented and introduced to the public for music recording. In the meantime, there is no doubt you will continue to enjoy listening to your favorite music on CDs and playing your favorite computer games on CD-ROMs.

Call the Disk Doctorl

1 Desperate computer users who 'lose' the data from their disks can get in touch with

experts who, for a fee, will recover the lost information. One of these experts is Dave Smith, who, some years ago, set up a company called fl3ve,5 Disk Doctor Service Ltd. Dave and a few of his friends work from home and give all the money they earn to charity. The fees are always the same, no matter how precious the data on the disk is. Some people, however, are so grateful that they send extra money to Dave or to the charities his company supports. One oil company offered him Li ,000 for his help and a vet sent him a blank check

2 It would be hard to put a value on the things rescued by the Disk Doctor. There have been disks containing medical research, television scripts, manuscripts of whole books, a comedlan,5joke collection, a solicitor' s papers for a court case, and even Margaret Thatcher,5itinerary for a visit to eastern Europe. For this last case, Dave was asked if he would go in person to Mrs. Thatcher's office 'for security reasons,!

3 Disks are usually sent to the Disk Doctor by post, but sometimes people are in such

a hurry that they can't wait for the post. Radio scripts have had to be rushed by taxi to

Dave's house because they were needed for broadcasting the next day, for example. When the material has been recovered, the disk is returned to the sender with a diagnosis and a prescription for avoiding the problem in future. One grateful client, an author put a 'thank you' to Dave in the front of his book.' Dave saved mc from a cardiac arrest' , he wrote 'But,,says Dave, 'most people don't take any notice ol the doctor's advice!'

Read Passage 2 and decide whether the following statements are Jrue or False. Write T for True and F for False against the number of each of the statements on your Answer Sheet

11. Computer users can get back their lost data from their disks without any payment in Dave's company

12. The company named Dave's Disk Doctor Service Ltd is set up by Dave Smith

13. Dave and his friends earn a large amount of money, but they spend none

14. According to the different value of the data on the disk, people need to pay different amount of money for saving them

15. Most people will take notice of the disk doctor' s . advice after the disk is repaired

16. hopeless _________ (paragraph 1)
