Network Attached Secure Disks NASD is 1997 2001 research project of Carnegie Mellon University , with the goal of providing cost effective scalable computer storage storage Bandwidth computing bandwidth . Overview NASD reduces the overhead on the file Server computing server file manager by allowing storage devices to transfer data directly to Client computing client s. Most of the file manager s work is offloaded to the storage disk without integrating the file system policy into the disk. Most client operations like Read Write go directly to the disks less frequent operations like authentication go to the file manager. Disks transfer variable length objects instead of fixed size blocks to clients. The File Manager provides a time limited cachable capability for clients to access the storage objects. A file access from the client to the disks has the following sequence The client authenticates itself with the file manager and requests for the file access. If the client can be granted access to the file requested, the client receives the Computer network network location of NASD disks and their capability. If the client is accessing the disk for the first time, it receives a time limited key for the establishment of secure communication to the disk. The file manager informs the corresponding disk using an independent channel. From now on, the client directly accesses the NASD disks by giving the capability it received and further data transfers go through the network, bypassing the file manager.

Refimprove date December 2008 merge Non RAID drive architectures discuss Talk Massive array of idle disks Merger proposal date April 2010 In computing , a massive array of idle disks more commonly known as a MAID is a system using hundreds to thousands of hard drive s for nearline storage of data . MAID is designed for Write Once, Read Occasionally WORO applications. In a MAID each drive is only spun up on demand as needed to access the data stored on that drive. This is not unlike a very large JBOD Just a Bunch Of Disks JBOD but with power management. Compared to Redundant array of independent disks RAID technology a MAID has increased storage density, and decreased cost, electrical power, and cooling requirements. However, these advantages are at the cost of much increased latency, significantly lower throughput , and decreased redundancy. Low drive utilization rates may actually reduce reliability in consumer oriented large PATA and SATA drives. ref name harris google Harris, Rick 2007 02 19 . http storagemojo.com 2007 02 19 googles disk failure experience Google s Disk Failure Experience , StorageMojo, Retrieved on 2009 12 19 ref Drives designed for multiple spin up down cycles e.g. laptop drives are significantly more expensive.

notability date August 2010 Reasonable Solutions is a company that, along with Software Labs and Public Brand Software played an important role in the early distribution of shareware . Reasonable Solutions sent out catalogs of disks with several DOS game s on each. The disks were designed to require little or no computer skills to use. A batch file , GO.BAT, on each disk displayed a menu of games that could be run by hitting 1, 2, 3, etc., which would in turn launch other batch files 1.BAT, 2.BAT, 3.BAT, etc. to run the games. In the early 1990s, the Internet became a prime competitor to Reasonable Solutions since it allowed shareware distribution without the cost and waiting time associated with ordering disks.

About computer music collections the Purple Motion album Musicdisk album demoscene Music disk , or musicdisk , is a term used by the demoscene to describe a collection of songs made on a computer. They are essentially the computer equivalent of an album . A music disk is typically packaged in the form of a program with a custom user interface , so the listener does not need other software to play the songs. The disk part of the term comes from the fact that music disks were once made to fit on a single floppy disk , so they could be easily distributed between friends and at demoparty demo parties . On modern platform computing platforms , music disks are usually downloaded to a hard disk drive . Songs in a music disk are typically composed with a tracker music software tracker , a type of program popular in the demoscene. Amiga music disks usually consist of MOD file format MOD files, while IBM PC PC music disks often contain multichannel formats such as Fast Tracker XM or Impulse Tracker IT . Music disks are also common on the Commodore 64 and Atari ST , where they use their own native formats. Related terms include music pack , which can refer to a demoscene music collection that does not include its own player, and chipdisk , a music disk containing only chiptune s, which have become popular on the PC given the large size of MP3 music disks.

The Beier variable ratio gear or Beier variator is a mechanical drive offering a variable gear ratio between input and output. The gear relies on the inter meshing of a number of thin disks. By varying their separation, the effective radius of one disk varies, thus changing the overall gear ratio. This principle is shared by a number of other variator mechanisms. An advantage of the Beier is that a large number of disks may be stacked on a common shaft, thus increasing its torque capacity for only a small increase in overall length. external image image1 http www.ganaengg.co.kr html s b.htm Diagrams of Beier drive The mechanism consists of a spring loaded stack of thin disks on a central shaft. Around this are arranged other stacked disk packs on a number of planetary shafts, usually three. These shafts are mounted on swinging arms, so that they may be moved in and out together. The central disks are thin, with a thickened rim. The planet disks are tapered across their radius, at an included angle of around 3 . When the disks are intermeshed, they thus only contact at the rim of the central pack, no matter what the spacing of the shafts. These planetary disk packs have a gear meshing with a gear on the swing arms fulcrum shafts, which in turn meshes with a central gear, used for the input drive. The central shaft is the output shaft and the gear is used as a reduction gear. When the disks are moved outwards, the central rim drives on the outside radius of the similar sized tapered disks and the overall ratio is around 1 1. As the swing arms are moved inwards, the tapered disks are forced between the central rims against their spring loading. The effective radius of the tapered disks is thus reduced and the gear ratio increases. The gear is made in a variety of ratio ranges, typically from 3 1 to 10 1. Overall efficiency is good, greater than 90 . Unlike most other variators, but in common with the Hele Shaw clutch , the Beier gear does not rely on friction between t ... more details
