Requirements for removable media storage devices (RMSDs) used with personal computers have changed significantly since the introduction of the floppy disk in 1971. At one time, desktop computers depended on floppy disks for all of their storage requirements. Even with the advent of multigigabyte hard drives, floppy disks and other RMSDs are still an integral part of most computer systems, providing: Transport between computers for data files and software. Backup to preserve data from the hard drive. A way to load the operating system software in the event of a hard-drive failure. Some RMSD options available today are approaching the performance, capacity, and cost of hard-disk drives. Considerations for selecting an RMSD include capacity, speed, convenience, durability, data availability, and backward-compatibility. Technology options used to read and write data include: Magnetic formats that use magnetic particles and magnetic fields. Optical formats that use laser light and optical sensors. Magneto-optical and magneto-optical hybrids that use a combination of magnetic and optical properties to increase storage capacity. This white paper discusses some of the current RMSD options available for handling today’s large files and massive software programs, as well as some future technology options. Optical systems are becoming the PC storage devices most likely to replace the floppy drive standard. CD-ROMs already are the media of choice for software applications. Zip and SuperDisk drives provide a good interim RMSD solution for recording requirements, and CD-RW drives will offer a more universal standard as their costs decrease. DVD-RAM and combination systems should provide high-end RMSD solutions using large-capacity DVD discs, and providing speed, durability, data availability, bootability, and backward-compatibility to CDs. Future enhancements, such as blue laser and multilayer fluorescent storage technologies, may contribute to this longevity wi
