Ultrafine high-performance metal particles and new calendering technology realize high output and high C/N
To assure dependable recording at the shortest wavelength of 0.29µm, Sony developed an ultrafine high-performance metal particle with the highest coercivity in the industry, half the size of the HDCAM tape particle and with about two times greater energy, and then packed it at high density on the tape. The non-magnetic lower double-layer structure permits a thinner magnetic layer, realizing +6dB high output compared to HDCAM.
Outstanding archival characteristics
To assure long term archival stability with consistently high output, Sony gives each high-performance metal magnetic particle a protective layer with an anti-oxidation effect. Sony also developed a special process that minimizes dimensional alteration shrinkage of the tape over time, thereby achieving high-precision tracking for accurate playback.
Durability to withstand repeated playbacks and edits, with outstanding tape transport stability
Sony's newly developed HR (High Rigidity) binder system confers the exceptional durability demanded in a broadcast professional tape, which must withstand repeated playback and editing. In addition, Sony's specially-developedbase film is ideally suited to high-performance metal tape transport; it is slit for high dimensional precision and assures tape travel stability to maintain optimum head contact.
