Page "Compact Cassette" Paragraph 20

Although the TDK-D C180 was produced for a decade ( 1972-82 ), it is very rare, because of several technical flaws.

The tape had to be so thin that it was nearly transparent and therefore had fewer particles to magnetize, resulting in a poor sound quality and even worse durability.

It required a strong motor to be driven, and had high wow and flutter.

Finally, it took a relatively long time to rewind.
