{"title":"Super Metal Cassette Tapes","description":"\u003ch2\u003eSuper Metal Cassette Tapes\u003c\/h2\u003e\n\n\u003cp\u003eSuper metal tapes occupy the very top of the Type IV hierarchy — formulations where manufacturers invested in ultra-fine metal particles, dual-layer magnetic coatings, exotic particle compositions including cobalt-alloyed iron, and precision shell engineering to push cassette audio performance to its absolute limit. These tapes require a deck with a Type IV (metal) position and reward the finest playback hardware.\u003c\/p\u003e\n\n\u003cp\u003eThe defining technology was the move to double-coated magnetic layers. Sony Metal ES (1987) was widely regarded as the first commercially available dual-layer metal cassette. Its magnetic layer combined a base coating and an ultra-fine upper coating, each engineered for different frequency ranges — the result was the highest MOL and lowest noise of any commercially tested cassette at the time of its launch. In Howard Roberson's landmark 1987 Audio Magazine test, Metal ES scored 88% — the highest of any type ever tested to that date.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSuper metal models in our collection\u003c\/strong\u003e span Sony Metal ES and Metal Master (loaded with Metal ES tape in a ceramic-shell housing), TDK MA-XG, Maxell Metal Capsule and Metal XS, and related ultra-performance Japanese-market metal tapes from the late 1980s and 1990s.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCollector note:\u003c\/strong\u003e Super metal tapes are NOS rarities.

These tapes require a metal deck position and reward the finest playback hardware.\u003c\/p\u003e\n\n\u003ch3\u003eWhat was special about the Sony Metal ES cassette?\u003c\/h3\u003e\n\u003cp\u003eSony Metal ES (1987) was among the first commercially available dual-layer metal cassettes. Its double magnetic coating — a base layer and an ultra-fine upper layer — achieved the highest 400 Hz MOL and signal-to-noise ratio of any cassette type tested to that date, according to Howard Roberson's Audio Magazine 1987 evaluation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is the Maxell Metal Capsule cassette?\u003c\/h3\u003e\n\u003cp\u003eThe Maxell Metal Capsule (1990–1991 JP) is a Japan-domestic flagship Type IV with ultra-fine metal particles offering improved dynamic range and noise performance over the standard MX-S line. It is rated by collectors alongside the MX-S and Metal XS as among the finest metal tapes Maxell ever produced.\u003c\/p\u003e\n\n\u003ch3\u003eAre super metal tapes suitable for regular use or just collecting?\u003c\/h3\u003e\n\u003cp\u003eBoth. On a well-calibrated reference deck with a good metal head, super metal tapes deliver extraordinary recording performance — the closest a cassette can come to open-reel quality. They are also genuine collector rarities, particularly Japan-market examples produced in limited quantities through the early 1990s.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I know if my deck can handle super metal tape?\u003c\/h3\u003e\n\u003cp\u003eAny deck with a Type IV (metal) position can record on super metal tape. For best results, a deck with manual bias and level adjustment will fully exploit the tape's capabilities. The tape's high output means some older decks may reach their electronic limits before the tape's own saturation point.\u003c\/p\u003e\n","products":[{"product_id":"sony-es-iv-1991-jp","title":"Sony ES IV Type IV - 1991 JP","description":"\u003ch1\u003eSony ES IV (1991 JP) Cassette Tape\u003c\/h1\u003e\n\u003ch2\u003e Sony ES IV  Cassette Description\u003c\/h2\u003e\n\u003cp\u003eThe Sony ES IV (1991 JP) cassette tape is a high-quality, professional-grade audio cassette designed for precise and reliable recording and playback.
