WeRecoverData.com - Web Archiving

Web archiving refers to the process of collecting and preserving information from World Wide Web. Web archives generally collect all types of Web contents including HTML Web pages, style sheets, JavaScripts, images, and video. Along with this, archivers collect metadata that includes access time, MIME type and content length. This information provides authenticity and provence required for researches and historical archiving purposes.

Massive Web archiving is done by employing Web crawlers for automated collection. Internet Archive is the largest Web archiving organization that employs crawling approach in Web archiving. The company is involved in an attempt to archive the entire Web. There are several software solutions and services commercially available to help individuals and companies archive their own Web content for legal or regulatory purposes.

Methods of Archiving
Some of the popular methods of Web archiving include remote harvesting, on-demand archiving, database archiving, and transactional archiving.

Remote harvesting is the method of collecting information automatically using Web crawlers. Examples of popular Web crawlers include Heritrix, HTTrack, Offline Explorer, and Web Curator.

On-demand Web archiving refers to archiving and retrieving Internet contents as per the specific requirements of the user. Popular services include WebCite, Archive-It, and Hanzo Archives.

Database archiving refers to the method of collecting underlying content of database-driven web sites by extracting the database content into a standard schema using XML.

Transactional archiving collects the details of actual transaction between a Web server and a Web browser. This method is used to preserve evidence of the content viewed on a particular Web page on a given date.

WeRecoverData.com - Rodime

Rodime was a hard disk manufacturer based in Glenrothes, Scotland. The company was founded in 1979 by a group of employees of Burroughs Corporation.

In 1981, the company started manufacturing 5.25" HDD OEM disk drives. Since then the company achieved a healthy growth rate. In 1983, Rodime became the first manufacturer of 3.5" HDD products.

Patent Issues
There had been a lot of controversy over Rodime's patented 3.5" form factor. Industry experts say that the first products to use the 3½" form factor were 3½" Floppy Disk Drives announced by Tandon and Shugart Associates in November 1982 at the Fall Joint Computer Conference.

It was unclear that time whether the patent should be issued on the form factor and also the set of dimensions that should be part of the form factor definition. Rodime had announced hard disk drives with outer diameter (OD) in the range of 92 to 96 mm. However, the industry agreed upon an industry standard disk for 3½" drives having and OD of 95 mm and an ID of 45 mm as early as 1984, even before the patent was issued in February 1986 and January 1987 respectively.

Rodime disks, which had 96 mm OD and 65 mm ID, had substantially smaller recording surface than the industry standard disk. This led to the failure of the product in the market.

Rodime also faced tough times because sales of the 5.25" drives were declining due to competition from dozens of 3.5" drive manufacturers. Rodime was not able to compete with the continuous improvements of its competitor drives in terms of performance and capacity. In 1991, the company filed for bankruptcy and stopped manufacturing of disk drives.

Shugart Associates was a computer peripheral manufacturer. The company was founded in 1973 by Alan Shugart. In 1977, Xerox purchased Shugart Associates. Xerox sold the brand name and some of the product line to Narlinger Group in 1986.

Shugart Associates dominated the floppy disk market in the late 1970s. It also became famous for introducing minifloppy disk drive.

Important products/achievements
Shugart developed the minifloppy 5¼-inch disk drive in 1976. The first model to be introduced was the 110KB SA-400. The SA-400 and the succeeding models received awesome response from the market, achieving shipments of up to 4000 drives per day.

With an aim to avoid development costs, Shugart approached Matsushita Communications in early 1980s for its half-height 5¼-inch drives. With this, Shugart became the largest floppy drive manufacturer in the world. In 1985, Xerox gave up Shugart's exclusive rights to the Matsushita half-height 5¼-inch floppy disk drives.

Shugart Associates introduced the "Shugart Associates System Interface" (SASI) in 1979. This interface was subsequently evolved in to the Small Computer System Interface (SCSI), which later changed the face of storage interface. The SASI engineering team was led by Larry Boucher, who along with his associates, later found Adaptec. The first standard process was completed in 1986 with ANSI standard X3.131-1986, also known as SCSI-1.
