Last fall, the DVD+RW Alliance dropped a bombshell on the optical storage industry when they announced Double Layer DVD+R technology. Developed by Philips Research and MKM (Mitsubishi Kagaku Media), this new technology increases the capacity of DVD+R media from 4.7GB to 8.5GB. While not quite double the capacity, it does allow users to store up to 8.5GB of data, 4 hours of DVD quality video or 16 hours of VHS quality video without the need to flip over the disc.
Advanced SCSI Programming Interface, or ASPI, is the glue that binds most major CDR software packages to the CDR drives. With so many different types of hardware out there, it's hard for software developers to add support in for each and every one of them. Adaptec, Inc. took that as a problem and created the ASPI layer that SCSI owners have grown to love.
