Why shouldn’t I just re-format my media on my computer?
Formatting can take many minutes; making the computer in operative and putting unnecessary wear on an expensive piece of equipment. When re-formatting media it is possible for tracks to be missed, this could cause read and re-write errors. A degausser will completely clear your media of all data in seconds.
August - 21 - 2012What type of degausser do I want?
The type of degausser needed is very much dependent on three main factors: 1. The type of magnetic media being used, such as audio tape, data tapes or hard drive. 2. The amount of media to be erased in a given period. 3. Are they a single or multi type media user? Magnetic media comes in many [...]
August - 25 - 2011What sort of erasure levels can I expect to get?
Using tape industry standard test: -90dB on magnetic media up to 750 Oe -75dB on magnetic media up to 1500 Oe
August - 24 - 2011What are the benefits of hard drive degaussing?
For the radio and television broadcast industry expensive media can be re-used many times, making cost effective savings. For the computer industry, storage media can be used many times without read or re-write errors. For security old storage media can be thrown away completely free of any sensitive information. Magnetic media duplicators can re-cycle over [...]
August - 23 - 2011What makes a degausser erasure so good?
In the manufacture of magnetic media one of the last production processes is for all magnetic media to be degaussed. This ensures that all the particles are orientated completely at random leaving the media free of any spurious signals. By degaussing magnetic media before re-using you are returning it to its original condition with all [...]
August - 22 - 2011Why can’t I run the media through my recorder using the erase button?
Erasing on a recorder ties up an expensive piece of equipment for maybe hours and puts unnecessary wear on the heads and drive mechanism. A degausser will give a deeper, more even erasure in seconds.
August - 20 - 2011Why can’t I just re-record over the media instead of hard drive degaussing?
Magnetic Media is made of oxide or metal particles that are orientated into a series of lines, which make up the signals. When you re-record only the particles that make up the new signals are re-arranged. This leaves some particles in the original orientation, which causes spurious signals. This can cause bad sound and picture [...]
August - 19 - 2011What is a degausser (bulk eraser)?
A degausser is a fast, efficient way to remove all audio, video and data signals from magnetic storage media such as tapes or hard drives.
August - 18 - 2011Degausser Information – Health & Safety
Currently there are no widely published statutory regulations limiting the magnitude of magnetic fields in the work place. (Non-ionising radiation). The NRPB (National Radiological Protection Board UK) have issued a guidance document (NRPB GS11, 1989). These guidelines are not statutory but set out to give a guide to those concerned with the possible effects of [...]
August - 17 - 2011Communications-Electronics Security Group (CESG) Approved Degaussers
Under the UK Information Technology Security Evaluation and Certification Scheme, managed by CESG, the security features of IT systems and products are tested independently of suppliers to identify logical vulnerabilities. This type of testing is known as security evaluation and it is carried out by Commercial Evaluation Facilities (CLEFs) against standardised criteria to a formalised [...]
