Pioneer introduced two new Blu-ray writer drives that are capable of writing 100GB Blu-ray XL discs at a speed of 4x CLV maximum. Dubbed as the BDR-PR1M and BDR-PR1MA, both Blu-ray players support up to 4x write for all BD discs, 6x for DVD and 16x for CD. Their main difference is that the BDR-PR1M can be used to check the quality of a recorded disc, right after burning.
The Pioneer BDR-PR1M and BDR-PR1MA will be released in November 2012 in Japan for about 220,000 Yen ($2,832) and 110 000 Yen ($1,416), respectively.
