a laser is used to read the information on the bottom of the disk
yes
Yes, optical disks use a laser beam to read and write data on the disk. The laser beam is focused onto the surface of the disk to detect and interpret the patterns of pits and lands that represent the data stored on the disk.
hard disk
No. A laser is not used to read or right to a floppy disk.The laser is usedto read and right data to an optical disk such as a dvd or cd. The floppy disk is a magnetic storage medium. A read right head is basically a small coil. When a current is passed thru the read/right head, itgenerates a magnetic field which aligns the small particles on the floppy disk in one of two directions. the direction of the particle indicates a 1 or 0which is the essence of data on a computer. to find out more details of the construction of a floppy disk and how data is saved, google floppy disk.
The motor in a CD player (or any "disk medium" player) is necessary to spin the CD at a speed that the laser pickup can "read" the data on the disk. As the laser pickup moves along the surface scanning the disk, it causes the motor to slow down as it gets further out on the disk so the data is still read at the correct speed. Or just the opposite, reading from the outside egde of the CD the laser needs to read constitantly so the disk motor speeds up for the smaller circumference of the data on the disk. A combination of elecltronics monitors the motor speed, the data being read and the location of the laser computing the time necessary.
Its probably that the PS laser reader cant read the disk or its missing the disk.
To get it to read UMD (don't take off the plastic casing) you have to put it in the disk compartment then it should read it and that's that If it doesn't read it you have a problem.
Main categories of optical laser disks are CD-ROM,WORM Disk/CD-Record able(CD-R) Disks,CD Read/Write(CD-RW) Disk,Digital Video(or Versatile)Disk(DVD).
Compact Disc-Read Only Memory (CD-ROM) drives use laser beams to read information on a rotating synthetic disk.
The Eye / Laser
No. Blu-Ray requires a different laser to read the disc.
