Japan's Magnetic Research Institute Puts a Hand-Assembled Type I Cassette on Sale 13 October at About $7

New cassette tape — actual new tape, assembled now rather than unearthed from a warehouse — remains one of the scarcer things in audio. So a modest announcement out of Tokyo this week is worth noticing: Magnetic Research Institute (磁気研究所), the company behind the HIDISC brand, has a Normal Position/Type-I cassette going on sale on Tuesday 13 October 2026 at about $7 (¥1,100), in limited quantities, at its own Akihabara shop. It is the second product in the company's new cassette line, following the chrome Type II that appeared in July.

The news was reported on 9 October by AV Watch and PHILE WEB, and as far as we can tell it has not been covered in English. It also comes with an important caveat for readers outside Japan: this is a single-store release in Tokyo. There is no stated online sale, no export arrangement and no distributor beyond the company's own counter.

What is being sold, and where

The product name is given plainly as "Normal Position/Type-I" — a Type I, normal-bias cassette, which AV Watch describes as using a high-density magnetic material. The price is about $7 per tape; PHILE WEB specifies that figure is tax-included. Quantities are limited, and PHILE WEB reports a cap of five tapes per customer at the store.

That store is MAG-LAB, Magnetic Research Institute's directly operated shop in Akihabara. Sales begin on Tuesday 13 October 2026. Before that, on Monday 12 October — a public holiday in Japan — the company plans a pre-sale from its booth at the CASSETTE WEEK MARKET 2026 event in Tokyo, where AV Watch says listening samples will be available so visitors can hear the tape before buying.

Notably absent from either report is a tape length. Neither article gives a C-60, C-90 or any other running time for the Type I, and the $7 figure is the only price published. No measured specifications were released either — no frequency response figures, no noise or output numbers.

Made one at a time, in-house

The more interesting part of the story is where the cassette comes from. Magnetic Research Institute assembles it at its own facility in Japan, the 磁気研カセットラボラトリ (Magnetic Research Institute Cassette Laboratory), using production equipment inherited from a long-established firm along with the skills of its engineers. The company's statement, as relayed by AV Watch, describes the tapes as being made one by one.

AV Watch's July report on the earlier Type II filled in the background on that facility: it began operating in 2020 and turns out roughly 20,000 cassettes a year. The company frames the whole enterprise less as a product line than as a preservation project — keeping domestic cassette manufacturing equipment and the know-how to run it from disappearing altogether. At 20,000 units annually, that is a workshop rather than a factory, which makes the limited-quantity, one-shop sales model less a marketing posture than a straightforward description of capacity.

One thing we are deliberately not saying: where the tape stock itself comes from. AV Watch does not specify it for the Type I, and the PHILE WEB passage on the subject was garbled in our copy. What is documented is that the cassette is assembled in Japan at the company's own laboratory.

The company's sound claim

As for how it sounds, the only characterisation available is the manufacturer's own, and we report it as such. The company says the tape delivers rich low and mid frequencies with strong high-frequency response, and that its frequency response is flat and well balanced across the full range, making it suitable for a wide variety of music. No independent measurements or third-party listening tests have been published, and no figures accompany the claim.

Packaging follows the house style established by the Type II: a black card sleeve with silver accents in place of the earlier gold, writable areas on both the front and back of the insert, and one index sticker in the box.

What came before: July's chrome Type II

The first release in the line, in July 2026, was a High Position/Type-II cassette — and its appeal rested on something that genuinely cannot be reproduced. It was made with chromium dioxide tape drawn from bulk "pancake" stock the company had kept in reserve. CrO2, as AV Watch notes, is a magnetic material developed by DuPont; chrome tape has long since ceased to be manufactured, so any new chrome cassette is by definition made from surviving stock.

That tape was shown at the Cassette Day event at CASSE Shibuya from 25 to 31 July 2026 before going on limited sale at MAG-LAB. It came in a black card sleeve with gold accents and used an Italian-made see-through shell. The cited article gives no price for it, so we are not quoting one.

Why a single-store Tokyo release matters

The cassette revival has mostly been a story about demand: rising sales of pre-recorded tapes, reissues, new releases on cassette by artists who were not born when the format peaked. Supply has been the harder problem. Blank tape production largely collapsed, and much of what circulates is old stock, re-shelled, or sourced from a very small number of surviving lines.

Against that, a Japanese company running inherited machinery at a few tens of thousands of units a year — and adding a second tape formulation to its catalogue within three months — is a small but real data point on the supply side. It will not be on a shelf in the United States, and the notes we are working from give no indication that it ever will be. But the equipment is running, the engineers are still there, and that is the part of the cassette story that is hardest to replace once it goes.
