That's VX - 1987 - EU
Quite possibly one of the best Type II cassettes ever made.
This uses cobalt doped ferric in the "triangle" shell, that people who remember That's fondly recall.
Don't really need any tweaking to make fantastic recordings.
That's were never common cassettes, usually only sold in Hi Fi shops or specialists. Made by Taiyo Yuden, who are now known for making the best blank optical media.
Always sought after, thanks to their great design, performance and reputation, these are never cheap.
Taiyo Yuden Co., Ltd. (太陽誘電株式会社 Taiyō Yūden Kabushiki-gaisha, translated as Sun Dielectric Co., Ltd.) is a Japanese materials and electronics company, situated in Kyobashi, Chuo, Tokyo, that helped pioneer recordable CD technology (CD-R) along with Sony and Philips in 1988. Founded 60 years ago, Taiyo Yuden currently operates factories in Japan, Singapore, Korea, China, the Philippines, Taiwan, and Malaysia.
They were well known for their recordable optical media, and were regarded by many to be the very best in the industry. In June 2015, Taiyo Yuden announced their intention to discontinue their recording media business by December of that year, citing market shrinkage, changing market conditions, difficulty while improving earnings and a hike in the cost of raw materials.
Taiyo Yuden branded products were not common outside Japan (where Taiyo Yuden media had a market share of about 60%) but unbranded CDs and DVDs were available from some online retailers. Rebranded Taiyo Yuden media could be found under Fujifilm, Fusion, Maxell (Maxell Music CD-R, Maxell CD-R Pro, and Maxell CD-R Music Pro (discontinued)), Miflop, Panasonic, Plextor, Sony (Sony Music CD-R (discontinued 2008)), TDK, and Verbatim Corporationbrands. In Japan, Korea and Greece, Taiyo Yuden was distributing its own brand "That's".
Taiyo Yuden has also developed the Autostrategy technology, a learning mode for DVD burners, for Plextor.In October 2008 Taiyo Yuden partnered with JVC to form JVC Advanced Media as a marketing plan to distribute Taiyo Yuden media globally under the JVC brand name.
In mid-2015, Taiyo Yuden announced their intention to have withdrawn from the optical media business (including CD-R, DVD-R and BD-R) by December of that year. Taiyo Yuden sold its disc manufacturing patents and equipment to CMC Magnetics, and today the media is manufactured by CMC under the CMC Pro brand.
