Don't panic, but the K7 lanes are numbered days

Forgive me MP15 owners, but the most practical, simple and efficient form of music media ever invented is the K7 Tapes, and with sadness we begin to realize that it's finally leaving us.

K7 tapes, millennia, millennia, K7 tapes

K7 tapes, millennia, millennia, K7 tapes

Who remembers the hell of memory cards a few years ago (SD, MiniSD, MicroSD, MMC, Memory Stick, Memory Stick Pro, Compact Flash, XD Card, Memory Stick Duo, PCMCIA, etc. etc.) He thinks that at the time of K7 lanes calmer, but in fact Techmoan subscribers know it was the same crash, years and years of incompatible formats competing with each other, lanes varying in speed, track count, quality.

The K7 Tape, a welcome adaptation to avoid the untrained name "Tape Tape", was introduced in 1963 as a welcome replacement for eight-track roll recorders and cassettes, this trick here.

Unlike the LP, the K7 tape was portable and hard to damage, it could be thrown into a backpack, carried in a pocket and handled occasionally. After Darwin's standardization of formats, the mismatch has dropped to zero, so you can buy or borrow a tape 100% sure it will be read.

The reduction in format was accompanied by an equally welcome increase in available music space, but more than that, smaller bands allowed for the creation of portable players, starting this revolution:

The Walkman was wonderful, but it was spoiled by the iPods of life, despite Apple fans' assurance that getting into the music business was a stupid and futile idea. Soon everyone stopped buying tapes, and the United States today has a unique K7 tapes factory, but thanks to nostalgic works like "Guardians of the Galaxy" and "Stranger Things", the tapes are coming back, though insignificant compared to even LP, sales only increased

Of course, it is a niche, no one in their right mind will trade Spotify for the 60-minute k7 tape and stroller that is now a mess, and the equipment is bleak. Or buy an expensive eBay strip deck or a filthy portable mono player, though. There is only one factory in China that builds mechanical modules for K7 tape players.

This scarcity of resources was compounded when National Audio Company, the only US company still producing k7 tapes, issued a statement to its customers: They are unable to obtain the raw material needed for a high-grade magnetic band, the iron oxide range. purity, or γ-Fe2At3

Naturally found in hematite, this form of iron oxide stabilizes in a cubic structure, and because of this (I think) has magnetic properties, making it ideal for use on K7 tapes.

It can also be synthesized from FeO (OH), but it is important that only one plant in the world refines γ-Fe.2At3 With the required cleanliness of the National Audio pen, and this plant underwent renovation in early 2019, late deliveries were already over 50 tonnes.

The plant has promised to deliver at least 11 tonnes by the end of October, but the problem is more serious. We have a single tape factory that depends on one supplier. In 2015 National Audio Audio sold $ 5 million, a drop in sales, and given that the raw material is only a fraction of that price, the Chinese don't make much money.

Soon it will be economically impossible to produce new tapes, as is the case with photographic films. Today there are 12 factories in the world that produce films, adapted to be the most adapted 35mm films for photo cassettes.

The nostalgia class has to be cautious, set up a good strip fund, and museums need to do the same thing. The march of time is cruel and never stops for anyone.
