Can an ordinary DVD burner use Blu ray discs?
Blu ray DVD disc track spacing decreases to 0.32mm, only half of the red DVD disc; and the recording unit - groove (or chemical transformation unit) the minimum diameter is 0.14mm, than the 0.4mm groove red DVD disc is much smaller. The storage capacity of Blu ray DVD single single disk is defined as 23.3GB, 25GB and 27GB, of which the highest capacity (27GB) is the current red DVD single-sided single disk capacity (4.7GB) of nearly 6 times, this is enough to store more than 2 hours of playback time of high-definition digital video content, or over 13 hours of play time television standard the program (VHS standard image quality).Prices vary from place to place. For the moment, blue light recorder is about 1200-2000 yuan, blue disc is 20-30 yuan or so, Blu ray player is about 1000 yuan.
Attached: Blu ray recorders and CD: the difference between blue light and ordinary burner burner: the current popular DVD technology with wavelength red laser and digital aperture 650nm for focusing lens 0.6, the disc thickness is 0.6mm. The blue DVD technology uses a blue laser with a wavelength of 450nm, and the focus spot size is reduced to a minimum by a digital aperture with a wide-angle lens ratio of 0.85. In addition, the disc structure of blue DVD using optical 0.1mm thick transparent protective layer, to reduce disk write arrhythmia during rotation due to tilt caused by reading, which reads the data more easily, and greatly improve the storage density may be provided.
No way。 The wavelength of the laser is different. You can only burn and play with a blue light recorder or Blu ray player.
