optical storage capacity

 In Sin categoría

The companies have cranked up the storage capacity on optical media to a stunning 3.3TB. The companies have cranked up the storage capacity on optical media to a stunning 3.3TB. Advantages of optical disk compare to magnetic disk: The storage capacity of the optical disk is more than a magnetic disk. 100 DVD-5’s is 470GB worth of data storage, and the cost-per-gigabyte of storage you buy here is also $0.04 per gigabyte. This leaves the data in the middle of the disc, which is necessary for DVDs to achieve their storage capacity. Disadvantages of the optical disk: The main disadvantages have cost both for the drive and the disks. Optical media can have a shelf life greater than 50 years. CDs can store up to 700 megabytes (MB) of data, and DVDs can store up to 8.4 GB of data. Scientists from RMIT University in Australia and Wuhan Institute of Technology in China have developed a radical new high-capacity optical disc called “nano-optical long-data memory” that they say can record and store 10 TB (terabytes, or trillions of bytes) of data per disc securely for more than 600 years. We can obtain transparent fluorescent tape by means of the simple dip method. In multi layer discs, semi reflective instead of reflective coatings are used for all layers except the last layer, which is the deepest one and uses a traditional reflective coating. This storage capacity is a clear advantage over the floppy disk storage media (a magnetic media), which only has a capacity … In this Letter, we show an ultralarge capacity for three-dimensional optical data storage inside transparent fluorescent tape using the two-photon absorption photo-bleaching method. Optical storage on the system provides an economical and efficient way to store and retrieve large amounts of information at a high performance level. If you were to use non-rounded numbers, here’s how it fares out with the prices listed above: HARD DRIVE: $0.039995 per GB OPTICAL: $0.0404042553191489 per GB The optical disk is physical storage than magnetic disks and can not be damaged easily. Blu-ray discs, which are the newest type of optical media, can store up to 50 GB of data. Optical storage devices offer advantages over other high-capacity storage such as microfilm and tape in that they have faster access times. Optical storage devices offer significant advantages over other high-capacity storages devices, such as tape and microfilm, with faster access times and a hierarchical-type file organization. Capacity, performance and price of optical storage devices are continually improving. The storage market is projected to grow to $100 billion by 2005, according to Jim Rothnie, senior vice president, product management, at EMC (Hopkinton, MA).
