Sony - Metal-XR Type IV Metal Position – 13 unused cassettes, including three 90-minute 2-packs Blank audio cassette - Multiple models

The Sony Metal-XR Type IV Metal Position audio cassettes are high-quality blank cassette tapes designed for audio recording. Type IV refers to metal tapes, which use a different magnetic material that offers improved high-frequency response, lower noise, and better dynamic range compared to Type I (ferric) and Type II (chrome) tapes. These features make Metal Position cassettes preferred by audiophiles and recording professionals seeking superior sound fidelity on analog formats. Unused cassettes, especially in packs or sealed sets, are of interest to collectors and enthusiasts for their rarity as new production of such tapes has ceased. The inclusion of several 90-minute tapes in 2-packs provides flexibility for extended recording and playback sessions, supporting music recording, voice, or data backup applications in vintage cassette decks.
