What is a DVD burner with a dual layer?
DVD burner with dual layer is a player of the optical disk and a recorder that can Use a DVD with a dual layer for playing and burning. Most modern DVDs The burners incorporate this function, including plans built into computers, And all models are also compatible with standard, single -layer media.
The advantage of the medium with a dual layer is that holding twice its data Single -layer counterpart. Standard one -sided single -layer DVD (DVD5) has a capacity of about 4.7 gigabytes (GB) while being one -sided, DVD with double layer (DVD9) can hold about 8.5 GB. The dual layer disk is Comfortable for high -resolution movies that fit on one disk Without having to reduce quality. Also both physical layers of data It is based on the same side of the disc so that the content can play directly Without the need to remove the disk to turn it over.
a commercial pre -recorded optical disk, whether CD or DVD, has the inner layer that is stamped by bumps and land that indicates those and zlyPro the exact return of digitalthe content of content. Bumps and landing It is located on a spiral track followed by an accurate laser, reflects deviations. When the laser hits the ground, the light bounces back on a a sensor indicating one. When the laser hits the wound, reflection It reflects from the sensor, which shows zero.
When a DVD burner with a double layer reads a double layer disk, a laser for reading regulates its focus around semi -transparent first layer of physical Data, for the next layer of data. This focus Laser reading may last a second or two, causing a momentary break Playback.
While a pre -recorded DVD and CD are sufficient land and bumps For those and zeros, writable media used for domestic enthusiasts Another method for recording and zeros. Rather than landing and bumps, and A layer of photo -sensitive dye is used.
When a DVD with a dual layer of data recording, it uses notation-earr Stronger than the laser reading. Enrollmentwarms the dye on Accurate points, causing it to become opaque. Where the dye is opaque, This will be interpreted as zero. Where the dye remains translucent allowing the laser to go through the semi -transparent, reflective Metal layer, one. When the first data song is recorded Write-Laler re-focuses his beam on a deeper, second layer of dye-supported dye Second layer of reflective metal, continuation of the burning process.
DVD Burner with a double layer can also burn to rewrite the media. Overwrite Optical discs use compounds of phase change changes that can be deleted and rewrite repeatedly. When a compound with a phase change briefly warms up to The melting point, de-strrystallizes, becomes liquid and opaque, remains in This condition even after cooling. This serves as a digital zero. If re -warm and held at another temperature (that's interesting cooler than the melting point), the compound re-cystallizing, becoming Reflective again. Digital is used in this state. Dual layer DVD Burner can use rewriteElna media to record television programs or movies for Later viewing in the same way were before Used, recycling of one tape.
dual layer burners are reasonably cheap and are available Home entertainment and computers are sold everywhere. Control units specification to verify the required input and output ports and whether Cables are included.
