What to do when a sony handycam cannot read new sony minidisc?

I own a Sony handycam 120x,


and i purchased Sony handycam DVD+rw 2.8 GB/go mini discs


but for some reasons the handycam says "disc error" ,


but other mini discs like Fuji film DVD-rds 2.8 GB 1x to 4x and Sony for handycam DVD-rw 1.4 GB work perfectly ,


so is there anything i can do to fix this problem ?|||I JUST GOT 2 POINTS
