Black/Black 52X 80-Min Double-Sided Colored CD-R 100-Pak (2 x 50-Pak) "DOUBLE-SIDED BLACK" High-Performance CD-R's! The NEW Premium, Professional Grade 80 Minute DOUBLE-SIDED BLACK CD-R Media are capable of record speeds from 1X to 52X. The world's first DOUBLE-SIDED BLACK CD-R media! Bottom (record side) of the cd-r is BLACK, while top (label side) is BLACK, too! Both sides of the cd-r are black! Note that the apparent color of the top and bottom of the cd-r will not be identical, due to the inherent nature of each surface. These cd-r's look great! Bring the black cd-r concept to a new level! These cd-r's are real "eye-catcher's" when used for sending out music, software demos, samples or making backups! ****Important Note****: Please note that 'double-sided' refers to both sides being colored, NOT both sides being recordable. Additionally, a very small percentage of MAC computer's recorders will fail to be able to read/write to any Colored/Black recording surface. 2 x 50-Pak = 100-Pak. Advanced "DOUBLE-SIDED BLACK" composition! Uses an advanced, Phthalocyanine dye (comparable to Mitsui branded cdr's).
