Pioneer DVR-112

1. Introduction

Pioneer enters the 18x DVD recording market with a new Super-multi DVD burner. The Pioneer DVR-112 DVD/CD writer will burn at a maximum speed of 18x with DVD-R/+R single layer media, up to 12x on DVD-RAM Ver2.2 [RAM2(Class1)] media, and is the first DVD burner that writes up to 10x on DVD-R/+R (DL). The drive is available in beige and black (DVR-112BK) in Europe as an OEM, while it is also available in Japan (retail version).

Pioneer has also released another version of the drive, without writing support for DVD-RAM, the DVR-112D (DVR-1810 in the U.S.).

Pioneer engineers claim that the DVR-112's combined specifications deliver one of the highest levels of all-round DVD-writing performance and quality currently available.

Let's take a look at the drive's specifications, which appear to be quite impressive.

Key features DVR-112
  • Writes and reads DVD-RAM, DVD-R/RW, +R/RW and CD-R/RW formats
  • Buffer under-run protection for CD/DVD
  • Performance Adjusting Firmware - automatically optimises the disc’s rotation speed depending on the user’s application – for example, if watching a movie or listening to music, the disc velocity is reduced in order to keep background noise to a minimum.
  • Multi-effect Liquid Crystal Tilt Compensator - further improves recording and playback characteristics by compensating for discs that are warped or of uneven thickness (operates at high speeds and with Dual/Double layer discs).
  • Ultra-DRA (Dynamic Resonance Absorber) - suppresses vibration caused by imbalanced discs.
  • Disc-Resonance Stabiliser - controls the airflow generated by the disc-rotation to minimise disc-warping effect that can occur when a disc rotates at high speed.
  • Max. 18x writing speed for DVD-R/+R*
  • Max. 10x writing speed for DVD-R DL (Dual Layer) and +R DL (Double Layer) Discs
  • Max. 6x writing speed for DVD-RW
  • Max. 8x writing speed for +RW
  • Max. 12x writing speed for DVD-RAM**

    * It is required to use a cable corresponding to U-ATA66 (80-wire conductor cable)
    **DVD-RAM Ver2.2 [RAM2(Class1)] media
