From The Free On-line Dictionary of Computing (30 December 2018) :

  Compact Disc Recordable
  
      (CD-R) A write-once version of CD-ROM.  CD-Rs can
     hold about 650 megabytes of data.  They are very durable and
     can be read by normal CD-ROM drives, but once data has been
     written it cannot be altered.
  
     Standard prerecorded CDs have their information permanently
     stamped into an aluminium reflecting layer.  CD-R discs have a
     dye-based recording layer and an additional golden reflecting
     layer.
  
     Digital information is written to the disc by burning
     (forming) pits in the recording layer in a pattern
     corresponding to that of a conventional CD.
  
     The laser beam heats the substrate and recording layer to
     approximately 250 C.  The recording layer melts and the
     substrate expands into the space that becomes available.
