Sony Electronics announced that it had begun to ship its single-layer blank Blu-ray optical media and that it would start delivering dual-layer discs at the beginning of June. The company also confirmed the rumor saying that the manufacturer plans to equip its computers with Blu-ray disc drives.

Sony is shipping 25-GB BD media, which will retail for about $25 each disc. The 50-GB versions of the media (BD-R and BD-RE) will be dual-layer discs that will be sold for $48 and $60, similar to pricing on TDK's or Panasonic's BD media.

It seems that, later this year, Sony will also release the internal BWU-100A drive, which will be able to handle both 25-GB and 50-GB discs, burning a full 25 GB disc in about 30 minutes. Retail pricing for the BWU-100A drive will be available later this year.
