![]() Some CD-ROMs use another type of data connection called SCSI which is a faster type of connection as well as the newer SATA connection commonly used with today’s modern hard drives. This is the same type of controller used with IDE hard drives. An IDE controller inside the computer sends instructions back and forth between the computer and the CD-ROM, telling the CD drive to send data to the computer. The CD-ROM drive gets its power from the computer’s main power supply. These incoming pulses are decoded by the microprocessor and then sent as usable data to the rest of the computer where it is processed and used. The reflected light pulses are read by a photo detector. This also applies to DVD drives as well although they work a little differently.Ī CD-ROM drive operates by using a laser to reflect light off the bottom of the CD or disc.
