Blu-ray Disc format, created high-definition video playback and storage, but extends to other applications such as personal computers, data storage, video game consoles, and similar consumer electronic devices.

In the blue wavelength of 405 nm erotic. Capable of recording high-definition DVD is 15GB and the largest of the Blu – ray may be registered in a single layer disc to 25 GB of data.

Sony Corporation of extreme values of different experiments, and try to 400nm (and shorter wavelength) and numerical aperture of the highest value.

Optical lens numerical aperture objective is the ability to focus on a specific distance and angle of light erotica. As for the high numerical aperture, the distance becomes smaller.

Record CD-ROM data capacity depends on the beam spot size erotic. This format is directly proportional to the wavelength of the beam is focused on sex. Thus, the data will be (more…)
