Patent number: 4315269Abstract: An optical recording medium comprises a light reflecting material which is coated with a light absorbing layer and overcoated with a 0.05-1 millimeter thick layer of an optically transparent and chemically and thermally stable material such as a silicone resin. During recording, portions of the light absorbing layer are ablated or melted by a modulated focussed light beam, thereby exposing portions of the reflecting layer while leaving the overcoat layer intact. Information is recorded in the form of a reflective-antireflective pattern. Dust particles and other surface contaminants settle on the upper surface of the overcoat layer, so far removed from the focal plane of the recording lens that their effect on the recording or playback signal is considerably reduced, and no defect is noticeable on the playback monitor.Type: GrantFiled: August 29, 1977Date of Patent: February 9, 1982Assignee: RCA CorporationInventors: Allen Bloom, Sidney S. Seffren, Alan E. Bell, Robert A. Bartolini

Patent number: 4101907Abstract: An optical recording medium comprises a light reflecting material coated with a light absorbing material which is coated with a transparent barrier layer and overcoated with a relatively thick transparent protective layer. During recording, portions of the light absorbing layer are ablated by a modulated focussed light beam, thereby exposing portions of the reflecting layer while leaving the barrier and overcoat layers intact. Information is recorded in the form of a reflective-antireflective pattern. The overcoat layer suspends dust particles far above the focal plane of the recording lens, thereby reducing their effect on the recording or playback signal. The barrier layer insulates the light absorbing layer and the overcoat layer from chemical and thermal interactions which might result in a decreased signal-to-noise ratio.Type: GrantFiled: August 29, 1977Date of Patent: July 18, 1978Assignee: RCA CorporationInventors: Alan Edward Bell, Robert Alfred Bartolini, Allen Bloom
