Sony Corporation announced it will introduce a built-in CD-R/RW drive [CRX175E] that employs a new technology called "Power-Burn" that ensures secure data writing onto CD-R/RW disks.
The shipment of [CRX175E] to PC makers and other manufacturers will begin from early September 2001, at the price of 20.000 Yen (167$).
Power-Burn is a new technology designed to prevent errors in writing data onto a CD-R/RW disk in a CD-R/RW drive by automatically setting up the optimum recording conditions for the media while automatically adjusting to the delay in data transmission from a host PC. Even if data writing onto a CD-R/RW disk is interrupted due to delays in data transmission from the host PC (buffer under-run), Power-Burn technology instantly controls and accurately connects the interruption and resumption points of the data recording to give continuous writing indispensable for CD-R/RW playback compatibility.
In addition Power-Burn automatically optimizes recording conditions for the CD-R/RW drive such as the writing speed and the strength of recording laser light?analyzing the disk quality by reading pre-recorded information like the recommended recording speed and the conditions of a recordable side of the disk.
The built-in CD-R/RW drive [CRX175E] realizes 24X high-speed CD-R writing while the adoption of Power-Burn gives stable writing. In general, the acceleration of writing speed of CD-R/RW drives increases the possibility of delay in the data transmission from the host PC, which causes buffer under-run. Because [CRX175E] stops its data transmission when buffer under-run occurs and resumes writing only after a sufficient amount of data has been transmitted from the host PC, it avoids writing errors.
With high performance in both of the timing of when to resume writing and the location of where to resume writing, [CRX175E] allows recorded data to be read out smoothly during playback. In addition, the [CRX175E] tests data writing in order to automatically set the optimal recording conditions for each recording media as it reads out the makerís pre-recorded information on the disk. When a large gap is detected between the center core of a recording media and the rotation axis of a drive, [CRX175E] automatically changes its recording conditions to a recordable writing speed.
