摘要： A small-sized optical disc drive includes one voice coil motor magnet within which a tracking coil and two focusing coils are disposed such that the tracking coil straddles the two poles of permanent magnets that are adjacently disposed. The two focusing coils are disposed on either side of the tracking coil, with each of the two focusing coils being only disposed over one of the permanent magnets.
