Definitions

  • a first 3 nm thick metal layer 31 formed of Cr was formed by sputter deposition process under inert argon atmosphere and then, also under the argon atmosphere, the 10 nm thick recording layer 3 composed of TeSeBi and further followed by a second 2 nm thick metal layer were formed.
  • the main 10 nm thick stabilizing layer 5 of boron was formed by reactive plasma with CO 2 .
  • carbon was sputtered using also reactive plasma with CO 2 .
  • a first SiO 2 adhesive layer 61 was deposited by plasma sputtering process under protective atmosphere and under the same conditions the second adhesive layer 62 was deposited on the lower side of the upper substrate 12.
  • Si alone was applied instead SiO 2 with the similar effect.
  • lower and upper parts of the disc 1 prepared in the above described manner were glued together by UV cured adhesive by injecting the adhesive between the adhesive layers of both rotating parts of the discs and by curing the joint by an UV lamp.
