CD (Compact Disc)
CD Technologies
CD technology is envisioned to cut background noise & frictions while it is “playing” where records & cassettes are having these problems . Both sides of the CD cannot be used like cassettes or records. 12 inch CD can inhold about 80 minutes (700 MB) digital data . Nowadays new high density empty CDs also can be recorded for 90 minutes (790-800 MB CDs) . The digital data in CDs are printed in spiral same way as records & gains more space but datas cannot be read & print in from outside to inside like records , it’s read & print in from inside to outside. If we see as capacity , a cd of 700 MB is equivalent to 1010 pcs 1,440 KB double density floppy disc.
