a laser is used to read the information on the bottom of the disk
yes
hard 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.
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.
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.
No. Blu-Ray requires a different laser to read the disc.
The Eye / Laser
There is always a hole in any disk. It allows the laser reader to completely envelope the informational side of the disk so that it can read the information needed to run the program. Don't worry, there is nothing wrong with your disk.
