Abstract
According to one embodiment, there is provided a storage device including a data converter, a recording medium, and an equalizer. The data converter converts data into sets of n number of four-ary symbols according to mapping rules in which 2or fewer types of bit labels are mapped onto the n number of four-ary symbols, where n is an integer of two or greater. Onto the recording medium, the converted n number of four-ary symbols are recorded in the form of a signal of one level among four levels. The equalizer equalizes a signal read from the recording medium into sets of the n number of four-ary symbols.
