Light Intensity Modulated Direct OverWrite technology uses a different write technology which significantly improves on the performance levels of earlier MO devices and claims to be a viable alternative to hard disk drives in terms of … [Read more...]
Magneto-optical drives – MO technology
As implied by the name, these drives use a hybrid of magnetic and optical technologies, employing laser to read data on the disk, while additionally needing magnetic field to write data. An MO disk drive is so designed that an inserted disk will be exposed to a magnet on the label side … [Read more...]
Magnetic Disk Technology
Magnetic devices like floppy disks, hard disks and some tape units all use the same underlying technology to achieve this. The media (meaning the disk as opposed to the drive) is coated with magnetic particles a few millionths of an inch … [Read more...]
Optical drives – WORM Write Once Read Many technology
Despite the floptical's failure to oust the traditional floppy disk, for several years it appeared likely that optical drives, which read/wrote data with lasers which are far more precise than the drive heads on a traditional hard drive, were destined to replace magnetic disk … [Read more...]
Floppy Disk Data Storage
In 1967, the storage group at IBM's San Jose Laboratories was charged with developing an inexpensive device to store and ship microcode for mainframe processors and control units. The device had to cost under $5, be simple to … [Read more...]
Holographic Data Storage
In late 1995 a joint university/industry/government consortium initiated the Holographic Data Storage System (HDSS) programme, with the initial goals of developing several key components for the system, including a high-capacity, … [Read more...]
