There are two types of magnetic tape carriers: tape reels and tape cartridges. Both types can be used for either analog or digital recording. Tape cartridges are normally used only for digital recording. TAPE REELS Tape reels are used on magnetic recorders that use a manually loaded tape supply reel and a separate take-up reel. A reel's purpose is to protect the magnetic tape from damage and. How fun!! The magnetic tape is amazing, I must get some. Thank you so much for putting links to all the print outs. I think this would be such a great thing to pull out while I'm making dinner for the kids to play on the refrigerator. I've put you as a favorite .

Data destruction has been defined in a variety of ways by technical publications and industry leaders. However, the term data destruction is often used interchangeably with data sanitization, and it can be difficult to determine which definition is correct.. Throw in phrases like physical destruction and data erasure, and the simple act of making sure your data is irrecoverable quickly becomes.
The magnetic tape was an improvement over the paper tape and punched cards. With a magnetic tape, a much larger volume of data could be stored. And the record size that could be stored on a magnetic tape was variable. (Previously, the record size stored on a punched card was fixed.) So, there were some important improvements made by magnetic tape. Coupled with its large capacity, magnetic tape storage is also cost-effective. It stems from magnetic tape being just that – a reel of thin plastic tape coated with magnetised material. Rob Sloan, cybersecurity research director at the Wall Street Journal, explains: “The total cost of ownership [of magnetic tape storage] per terabyte is.

Kryder Data Storage Systems Center, Carnegie Mellon University, Pittsburgh, PAUSA The erasure characteristics of Cr02, Co-y-Fe, Ba ferrite, metal-evaporated and metal particle tapes were Cited by: 3. Erasure requirements and ease-of-erasure categorization are less refined for magnetic-storage disks than for magnetics tapes.
Effective erasure of magnetic tapes. book Tapes are used frequently for interchange and thus must meet coercivity specifications. Standard-and double-density floppy disks generally are rated at Oe. and their erasure by type I degaussers is a common practice. Magnetostriction is positively employed for the erasure of unwanted print through signals on magnetic tape (IASA-TC 04, ).
Contrary to widespread fears, magnetic information does not vanish with time. Properly produced, stored, and handled magnetic tapes will not lose their magnetic properties within historically relevant periods.
Designed to provide a cost-effective facility to erase a variety of common video and data magnetic media formats, the V94 tape degausser will appeal to anyone in the video and data industries who requires a low cost, compact eraser to handle small to medium quantities of audio cassettes, cartridges or VHS tapes.
Degaussing is an effective technique to make data unrecoverable from magnetic tapes or hard drives. The degaussing equipment uses the physical method of data destruction, based on the impact on the drive of a powerful electromagnetic pulse.
As a result, all magnetic domains of the carrier are uniformly magnetized to a saturation state. For example, the strongest print signal on a C cassette running at ips is about Hz ( Hz for a C), while an open-reel tape recorded at ips would have its strongest signal at Hz if the tape were a professional tape with a mil base film or Hz if the tape were a consumer version with a base film of mil thickness.
If you own a lot of video, audio and digital cassettes, you need to keep them far away from strong magnets. Unless, of course, you'd like to erase these tapes. Then, magnets become very useful tools.
Processing material stage where magnetic security strips are applied to books. The Compact Cassette or Musicassette (MC), also commonly called the cassette tape, audio cassette, or simply tape or cassette, is an analog magnetic tape recording format for audio recording and was developed by Philips in Hasselt, Belgium, and introduced in September Compact Cassettes come in two forms, either already containing content as a prerecorded cassette.
Being an industry standard unit for top government departments, the SDD Master packs a power gauss force destroying data stored in all hard drive formats and tapes.
It goes without saying that the SDD Master Hard Drive Degausser is the ideal solution for those seeking to prevent data from falling into the wrong hands, and protecting. Developed as a total data destruction solution, the Ontrack Eraser Degausser is a do-it-yourself hardware solution for large volumes of damaged or end-of-life magnetic media.
Specific Ontrack locations now offer shredders for the safe and effective destruction of. Field data of the erasure process including timestamps, voltage, field strength are recorded for certification and audit purposes and a copy issued to the client.
We use a 12, Oe magnetic flux capable degausser to destroy the data on the tapes which have typical coercivity values of Oe.

Erasure of Magnetic Tape A brief look is taken at several parameters of the erasing system of a magnetic tape recorder: head losses, remanence vs erasing current, and gap material and size.
A re-recording phenomenon is studied, and some measuring problems are discussed. The Oersted rating (abbreviated as Oe) is a mathematical value ascribed to the magnetic field strength or intensity of an object, such as a unit of magnetic media (tape cartridge or hard drive).
The term was named for Hans Christian Ørsted (14 August, – 9 March, ), a Danish physicist and chemist, best known for discovering that. Magnetic tape should receive the same kind of care that you would give to a valuable book or important photograph.
In general, handle the tapes with care, keep them clean, and apply common sense: Use and store magnetic tape reels and cassettes in a clean environment.
The Ampex Recording Media Corporation, a U.S. magnetic tape manufacturer, has developed many informational and training materials about magnetic tape.

It’s never mentioned as an option for erasing hard drives, not even pre-disposal. I suspect that the magnetic field required to erase a modern hard-drive platter is much higher than that required to er.Magnetic tools can signal locations on a map, keep track of time with in/out boards, and signify of progress on performance trackers.
Magnets come in many shapes and sizes and indicate important eye-catching information. Simple write-on tools can be used to create unique magnets that meet your specific professional and personal needs.Finally, Mediatec offers a complete line of data security, degaussing equipment for secure erasure of your sensitive, personal or company confidential data from magnetic media such as data tapes and Hard Disc Drives.
