[edit] Sequential access
Hi "K", I agree that sequential access is an important subject to cover for this topic. I moved the previous text to a subsection of 'Technical Details (and edited it) because the file system stuff is a little more technical than an average reader might be interested in. Let's put a general sentence or two in the opening section and put the more specific file layout details in the technical section. -- Austin Murphy 21:05, 30 March 2007 (UTC)
- Gosh, I tought you've removed it completely. It slipped my attention that you've just moved the text, sorry. --Kubanczyk 12:50, 3 April 2007 (UTC)
[edit] Redirected Data tape cartridge
A merge of content from the Data tape cartridge article was suggested, and I believe that it is a good idea - there really isn't anything in that article that is not already (or could not already be) covered in this one. However, I had trouble figuring out where, and if, the data from that article should be placed in this one. Here is the content from Data tape cartridge:
Information storage in year 1949 meant books, filing cabinets or punch cards. Tape cartridge was the stuff of science fiction. The limitations of punch cards were becoming obvious. The data storage problem as acres of filing cabinets filled with punched cards containing Social Security data echoed that a more compact means of storing data needed to be developed. The emergence of magnetic tape in 1952 by IBM was a big leap in terms of data storage. Throughout the 1950s and 60s, magnetic tape units offered successive improvement in data storage.
IBM produced the first automated data tape in 1974 bringing with it great innovations that in turn led the technology to a newer heights of data storage. One breakthrough was the introduction of 5.5 inch square data tape cartridge storing up to 200 MB data and executing at the rate of 3 MB/s requiring less than half of the floor space of an equivalent installation of its predecessor technology – magnetic tape units - from just a decade earlier.
Data tape cartridge was widely used in the early 70s and 80s for Data storage (a format of storing and backing up computer data on a storage device). The drawback is that tape drive must spend a considerable amount of time winding tape between reels to read any one particular piece of data. As a result, tape cartridges have very slow average seek times. However, it replaced many of the demerits of its predecessor technology (magnetic tape) with its high speed, non- bulkiness, low cost and stability. Now-a-days, we use the same technology of data tape cartridge in terms of 4 mm/8 mm data tapes, mini DV, VHS video etc.

I am unfamiliar with this subject. Is there any information contained above that should be placed in the Magnetic tape data storage article? I know that the article I've redirected had major tone issues, but is there anything factual that we should place into this article from it that isn't already present?

[edit] Tape Lifetime
It would be good to have some comments (or a reference to, for instance, Digital_permanence) about shelf life of the media, possibly compared with other media (notably hard drives and flash). —The preceding unsigned comment was added by 206.168.13.209 (talk) 14:34, August 22, 2007 (UTC)
