Vinpower knows how important it is to have recordable media that is dependable, more compatible and holds up over time. That is why Vinpower joined with Verbatim to offer the professional Gold standard grade 4x BD-R LTH Gold duplication quality media using the top of the line AZO dye. These discs provide the greatest compatibility amongst writer drives and players (both old and new). That means, because of the AZO dye, the 4x BD-R LTH Gold is far less likely to fail during the duplication process. That is true regardless of the recording drive used, which will give it a much greater rate of playback, regardless of the type and age of the player. Additionally, the AZO dye does not degrade like the less expensive versions used in most other common recordable medias, so that means that the content stored on the discs will be readable far longer than those less expensive discs.
