On this blog, I will share my love with the world of Personal Stereos. This is limited only to Personal Stereos and Minidisc Players and maybe some other unique gadgets. The common rule with all those Personal Stereos is their State-of-the-Art; High-Quality Sound, Excellent build and Unique design - in other words, Personal Hi-Fidelity Analog music players for the soulful man. The main interest (but not limited to) in Walkmans is AIWA Personal Stereos from their early years' product line from 1984 to 1991. The main interest in Minidiscs (but not limited to) is Sharp Minidiscs. I will post pictures of rare Walkmans and Minidiscs with information. Thank God for making all this possible, I hope you all will enjoy my blog.
Note: I started this blog in 2011 to offer a unique perspective for educational purposes in the world of personal Stereo. I will gladly share most of the info regarding the gadgets displayed on this blog.

Sharp MD-MT821



~~~~ MD-MT821 ~~~~ 



MiniDisc [MD] is a magneto - optical disc-based data storage device initially intended for storage of up to 74 minutes and, later, 80 minutes, of digitized audio. In the form of Hi-MD, it has also developed into a general-purpose storage medium. MiniDisc was announced by Sony in September 1992 and released that November for sale in Japan and in December for the USA and Europe. The music format was originally based exclusively on ATRAC audio data compression, but the option of linear PCM recording was later introduced to attain audio quality comparable to that of a compact disc. MiniDiscs were very popular in Japan but made a limited impact elsewhere. {wikipedia}

~~~~~ PMD-R77 ~~~~

Pioneer PMD-R77 - OEM version of the Sharp MT821

The Pioneer PMD-R77 is a unique and very rare version of the MT821. This MD was sold exclusively in Japan. Regardless of sound quality and features the PMD-R77 have a major issue. out of 3 players I had encounter all of them have a malfunction and displayed: "NO DISC" I believe the lens are the fault of this OEM version. the remedy for that is to replace the internal mechanism of the PMD-R77 with a working T821 mechanism. this MD recorder is one of my favorite of my MD collection.
