They require unusually low bias, and even then only few of them perform on par with quality Type I tapes. In the beginning of the s, gradual technological improvements of the previous decade resulted in the second generation of Type I tapes.
These tapes had uniformly needle-shaped, highly orientable particles HOP of much smaller size, around 0. The first microferric TDK SD was introduced in , and in Pfizer [e] began marketing patented microferric powder that soon became an industry standard. Thus, for example, TDK ensured that its premium microferric AD cassette was always ahead of entry-level microferric D, having finer particles and lower noise. Overall, superferrics are a good match to Type IV especially in recording acoustical music with a wide dynamic range.
Type II has been historically known as ' chromium dioxide tape' or simply 'chrome tape', but in reality most of Type II cassettes do not contain chromium.
In the middle of s DuPont created and patented industrial process of making fine ferromagnetic particles of chromium dioxide CrO 2. First CrO 2 tapes for data and video appeared in The combination of low noise CrO 2 tape with electronic noise reduction brought a revolutionary improvement to compact cassette sound, almost reaching high fidelity level. However, CrO 2 tape required redesign of bias and replay equalization circuitry, and early formulations allegedly caused excessive head wear.
These problems were solved during the s  but three unsolved issues remained: the cost of making CrO 2 powder, the cost of royalties charged by DuPont, and the pollution effects of hexavalent chromium waste. CrO 2 tape does not tolerate overload: onset of distortion is sharp and dissonant, so recording levels should be set conservatively, well below MOL.
CrO 2 cassettes are best fit for recording dynamic music with rich harmonic content and relatively low bass levels;  their dynamic range is a good fit for recording from uncompressed digital sources  and for music with extended quiet passages. After the introduction of CrO 2 cassettes Japanese companies began developing a royalty-free alternative to DuPont's patent, based on already established cobalt doping process. By ferricobalt formulations took over the video tape market,  eventually they became the dominant high-performance tape for audio cassette.
In consumer markets chrome coexisted, as a distant second, with "pseudochromes" until the very end of cassette era. Ferricobalt technology developed continuously; in the s Japanese companies introduced 'premium' double-layered ferricobalts with exceptionally high MOL and SOL, in the middle of the s TDK launched the first and only triple-coated ferricobalt, the SA-XS.
Coercivity of iron-cobalt MP mix, precipitated from aqueous solutions, depends on cobalt content. In Sony introduced double-layer ferrichrome tapes, having a five-micron ferric base coated with one micron of CrO 2 pigment. These expensive tapes never gained substantial market share, and after the release of metal tapes they lost their perceived exclusivity.
MP tapes, particularly top-of-the-line double coated tapes, have record high midrange MOL and treble SOL, and the widest dynamic range coupled with lowest distortion. Unlike previously described wet coating processes, metal evaporated ME media are fabricated by physical deposition of vaporized cobalt or cobalt- nickel mix in a vacuum chamber.
ME coatings, along with barium ferrite , have the highest information density of all rerecordable media. From Wikipedia, the free encyclopedia. Differences in tape colour of most common tape formulations, top to bottom: ferric, ferricobalt, chromium dioxide and metal particle cassettes. Standardized notches for automatic tape selection. The horizontal span shows coercivity - how much flux it takes to magnetize the tapes.
These are typical values for a microferric cassette. Users can also take advantage of its Low Noise surface to provide a suitable outlet for music, as well as different types of audio. Bring back the classics as you use your cassette tape recorders with the UR to record different audio.
Gain excellent quality results as you record audio for books, song covers, or other types of media. Sometimes, blank cassette tapes are finicky as they might not be compatible for use with certain types of tape recorders. The bump in price is primarily due to these blank models being chrome tapes. Hence, it offers better quality recorded audio than most. Prince Lincoln Thompson. Money In My Pocket. Dennis Brown. Big Seven. Judge Dread.
