Abstract
According to one embodiment, there is provided a storage device including a controller circuit and a storage medium. The controller circuit includes a first conversion circuit and a second conversion circuit. The first conversion circuit converts data into M-ary symbols where M is an integer of 3 or more. The second conversion circuit converts respective ones of the converted n samples of M-ary symbols into signals with L-patterned pulse width where n is an integer of 2 or more. The storage medium stores the converted n samples of signals with L-patterned pulse width. The controller circuit further includes an equalization circuit that equalizes signals read from the storage medium into the n samples of M-ary symbols.
