Hej, här är lite mer info om den senaste remasteringen från Japan:
Blu-spec CD format boasts a new approach to the faithful reproduction of music by utilizing the leading edge blue laser diode technologies optimized for the manufacturing of Blu-ray. During the manufacturing of CD, laser beam is pinpointed to encode data on the microscopic tracks molded on the polycarbonate plastic constituting the surface of the disc.
Compared to the conventional laser beam used for the manufacturing of standard CD, the blue laser beam used for the manufacturing of Blu-spec CD has a shorter wavelength, allowing more accurate encoding of the data. The use of the laser also eliminates the need to use cooling fans that cause vibrations. Furthermore, polycarbonate plastic optimized for Blu-ray is used to ensure accurate reading of the data. Amazingly and importantly, Blu-spec CD format is fully compatible with standard CD players.
