Released in April 1987. The half is made entirely of ceramic and also features a ceramic tape guide, also found in the HF-PRO and UX-PRO. This aims to reduce modulation noise, which causes sound muddiness due to uneven contact between the tape and the head during recording and playback, and external vibrations from the deck [citation needed]. (Advertisement from April 1987) Also, due to the material of the half, it was no longer possible to break off the tabs, so a new idea was implemented: a plug-in type that could be removed and reattached. The writing on the half, including the following series, is all printed using instant lettering. The items for sale are three tapes, all of which have been recorded on. I don't have a playback device, so I don't know what's recorded on them. However, as you can see in the photo, one tape has a song index. The other two are 38 years old, so I'm sorry, but I don't remember. Please understand that what is recorded is a surprise upon purchase. The cassette bodies are clean, but the cases have scratches. Please understand.
