“超8”是1989年4月商品化最先进小型录象机。其正式名称为“高带8mm 录像机”。高带8mm 录象机,是由 SONY 等10家公司组成合作开发组共同开发的。经商定,高带8mmVTR 被命名为“Hi8”。“Hi8”格式可使用两金属磁带,图象记录频带白峰值提高到7·7MHZ、频偏扩展到2·0MHZ,使水平清晰度提高到400线以上,并大幅度提高了信噪比Hi8格式是超越了 Betamax 及 VHS 的崭新格式,这是因为尽管最近 VHS 发展到S—VHS、Betamax 发展到 EDBeta,但是,由
“Super 8” is the most advanced miniature video recorder commercialized in April 1989. Its official name is “high-band 8mm video recorder.” High-band 8mm video recorder, is composed of 10 companies such as SONY co-development team jointly developed. It is agreed that the high band 8mmVTR is named “Hi8”. The “Hi8” format allows the use of two metal magnetic tapes with an increase in the white peak value of the image recording band to 7 · 7 MHz and the frequency offset to 2.0 MHz, which increases the horizontal resolution to above 400 lines and greatly improves the signal-to-noise Hi8 format Is a new format that goes beyond Betamax and VHS because Betamax has grown to EDBeta despite recent VHS developments to S-VHS. However,
