  A typical reading method of an external storage medium drive is an optical pickup method using a laser diode. CD-R / RW drives and various DVD drives differ greatly from magnetic disk drives (floppy disk drives and hard disk drives) by using light, not magnetic fields, for data reading from the data surface of external storage media. To read the data.

  CD-R / RW reads irregularities (referred to as pits) formed on the surface of the disk by reflection of laser light and discoloration / degeneration of the recording layer.

  The laser beam emitted from the laser diode passes through an optical system composed of a series of lenses and the like, focuses on the data surface, and the laser beam reflected from the data surface returns to the detector. The system sends a reflected beam to the photodiode, which detects the amount of light in the reflected beam. The read data is converted into a bit pattern by decoding the pattern on the data surface by a photodetector.

  Next, the external storage medium drive includes data writing means for writing to the external storage medium.

  The external storage medium writes and stores data by imparting physical irregularities on the surface and changing or altering the recording layer.
