The Hyper CD-ROM is a claimed optical data storage device similar to the CD-ROM with a multilayer 3D structure, invented by Romanian scientist Eugen Pavel. The technology is supposedly similar to FMD discs. The bit of data being held as a change in fluorescence characteristics once irradiated with one or two lasers.
That said, the price of high-capacity drives has fallen rapidly, and this is indeed an effect of density. The highest capacity drives use more platters, essentially individual hard drives within the case. As the density increases, the number of platters can be reduced, leading to lower costs. Hard drives are often measured in terms of cost per bit.
Hi-MD is a magneto-optical disc-based data storage format. It was a further development of the MiniDisc. [1] With its release in later 2004, [2] came the ability to use newly developed, high-capacity 1 gigabyte Hi-MD discs, in the same dimensions as MiniDisc. [2] The last recorder and player was discontinued in 2011. [3]
The Recordable Audio CD is typically somewhat more expensive than CD-R due to lower production volume and a 3 percent AHRA royalty used to compensate the music industry for the making of a copy. [98] High-capacity recordable CD is a higher-density recording format that can hold 20% more data than conventional discs. [99]
The Zip drive is a "superfloppy" disk drive that has all of the standard 3 + 1 ⁄ 2-inch floppy drive's convenience, but with much greater capacity options and with performance that is much improved over a standard floppy drive. However, Zip disk housings are similar to but slightly larger than those of standard 3 + 1 ⁄ 2-inch floppy disks. [2]
The CD-MO standard allowed for an optional non-erasable zone on the disc that could be read by CD-ROM units. Data recording (and erasing) was achieved by heating the magneto-optical layer's material (e.g. Dy Fe Co or less often Tb Fe Co or Gd Fe Co ) to its Curie point and then using a magnetic field to write the new data, in a manner ...
The 120 mm (5") disc has a storage capacity of 74 minutes of audio or 650 Megabytes (MBs) of data. CD-R/RWs are available with capacities of 80 minutes of audio or 737,280,000 bytes (703.125 MiB), which they achieve by molding the disc at the tightest allowable tolerances specified in the Orange Book CD-R/CD-RW standards. The engineering margin ...
Internal and external 1GB Iomega Jaz drives with media. The Jaz drive [1] [2] is a removable hard disk storage system sold by the Iomega company from 1995 to 2002.. Following the success of the Iomega Zip drive, which in its original version stores data on high-capacity floppy disks with 100 MB nominal capacity, and later 250 and then 750 MB, the company developed and released the Jaz drive.
