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 3: 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 bag. 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 $10.79 is for each tape, and not for the 2 tapes!
NOTE 4: 90 Minutes: Just like the ones above on "Note 3", this is the earlier version of this 1979 run of "D" tapes. These do not have the diagonal line "Dynamic Series" written on the front of the J-Card. These are stacked differently than those of "Note 3". These however, will be sold in their original 2-tape packaging as seen here. These are 100% new tapes. See pictures, the cassette on top shows a hairline crack on the front side case. Price of $18.79 is for both cassettes. Only 1 set available.
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Since 1997 TDK has gradually withdrawn from the production of compact cassettes.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]
