TDK D - 1979 - JP
Legendary and reliable.
Honestly, the later and cheaper ones are just as good, so you'll really only want this version for nostalgia or collecting purposes.
A big of negative bias and NR, and this is a very musical cassette.
NOTE 1: 60 Minutes: "Dynamic Series": Made in Japan for all markets. Only 1 available. Heavily scuffed and two tiny rips repaired. All other blemishes can be seen in the pics shown.
NOTE 2: 90 Minutes: "Dynamic Series": Made in Japan for all markets. Only 1 available. Very clean.
NOTE 2: 90 Minutes: This is the earlier version of this 1979 run of "D" tapes. Only available. These do not have the diagonal line "Dynamic Series" written on the front of the J-Card. They are originally sealed inside their 2-tape packaging. They will be properly and individually re-sealed if you buy only one, or you will get them in their original 2-tape packaging as seen here, if you are quick enough to buy both of them. These are 100% new tapes, never recorded on or tested on. Price of $11.79 is for each tape, and not for 2 tapes!
About TDK:
TDK was founded in Tokyo, Japan, on 7 December 1935 to manufacture the iron-based magnetic material ferrite, which had been recently invented by Yogoro Kato and Takeshi Takei.[3] In 1952 and 1957 they began production of magnetic tapes, with compact cassette tapes following in 1966; it is for these that the company is most widely noted. TDK used to manufacture an extensive portfolio of magnetic and optical media, including several formats of videotape and blank CD-R and recordable DVD discs until the recording business was sold to Imation in 2007.
Operations in the USA began in 1965 with a New York City office,[4] and European operations began in 1970 with an office in Frankfurt, West Germany.[5]
Since 1997 TDK has gradually withdrawn from the production of compact cassettes. First with the MA-X and AR ("Acoustic Response"), then the AD ("Acoustic Dynamic") and SA-X line in 2001 and 2002 respectively, then the MA ("Metal Alloy") line in 2004. The SA ("Super Avilyn") and D ("Dynamic") lines were withdrawn in 2012 under Imation ownership. Industry trends see the company moving into new forms of media; in 2004 TDK was the first media manufacturer to join the companies developing BD post-DVD technology.[4] TDK operated a semiconductor division in California for about a decade, but divested it in 2005.
In late 2007, Imation acquired TDK's recording business, including flash media, optical media, magnetic tape, and accessories, for $300 million.[6][7] This also included a license to use the "TDK Life on Record" brand on data storage and audio products[8] for 25 years.[6] In September 2015, Imation announced that it had agreed to relinquish this license[9] and would cease selling TDK-branded products by the end of the year.[10]
