WHAT IS A JAPAN "MINI-LP-SLEEVE" CD? Have you ever lamented the loss of one of the 20th Century's great art forms, the 12" vinyl LP jacket? Then "mini-LP-sleeve" CD's may be for you.
Mini-sleeve CDs are manufactured in Japan under license. The disc is packaged inside a 13.5MM X 13.5MM cardboard-sleeve, precision-miniature replica of the original classic vinyl-LP album. Also, everything else packaged with the original LP is precisely replicated and included, such as gatefolds, booklets, lyric sheets, posters, printed LP sleeves, stickers, embosses, special LP cover paper/inks/textures and die cuts. An English-language lyric sheet is also included, even if the original LP did not have printed lyrics.
Then, there's the sonic quality: Often (but not always), mini-sleeves have Japan-dedicated remastering (20-Bit, 24-Bit, DSD, K2 or K2HD, and/or HDCD), and can often be superior to the audio on the same title anywhere else in the world. There also may be bonus tracks unavailable elsewhere.
Each Japan mini-sleeve has an "OBI", a Japan-language promotional strip. The OBI often also lists the original album's release date, the Japan street date of that particular disc, the catalog number, and mastering info. Bonus tracks are always only listed on the OBI, maintaining the integrity of the original LP artwork.
The enthusiasm of mini-sleeve collecting must be tempered, however, with avoiding fake copies of Japan `sleeves manufactured in Russia and distributed throughout the world, primarily on eBay. They are inferior in quality, worthless in collectable value, a total waste of money, and should be avoided at all costs.
Also, there are older Japan mini-sleeve releases that have been supplanted with newer ones, usually with updated audio (such as JVC-Japan replacing older K2-mastered titles with new K2HD mastered releases).
All mini-sleeve releases are limited edition, but re-pressings/re-issues are becoming more common with some of the Japanese companies (but, again, not always). Mini-sleeve collecting can get expensive quickly, so, if you're a novice, it is highly advisable to seek the advice of an experienced `sleeve collector!
