Tray
Board, Disc
noun, suffix
The kanji and the word are the same! This word also means board and disc, which makes sense if you think about it. Boards you play games on are basically just trays for the pieces, and discs go inside boards (like records) for storage.
The reading is the same as the one you learned with the kanji!
私はビートルズのビニール盤を収集しています。
I’m collecting the Beatles’ vinyl records.
