Maxell has introduced a patented Blu Ray disc cleaner they call Wind Tunnel Technology. Unlike a conventional brush disk cleaner, which can damage a Blu Ray playerdisk, the Wind Tunnel cleaner uses airflow to eliminate dust and other particles on the disk. br The Blu Ray disk cleaner can also be used on PSP3 and X-box as well. In addition to the Blu Ray cleaner, Maxell has also developed a 6x recording and 25GB recordable disk.
