Abstract
Apparatuses and methods for detecting error events in a codeword reproduced by perpendicular magnetic recording medium (PMR. The method includes: generating cyclic redundancy check (CRC) parity bits based on a generator polynomial for a source information sequence to be recorded on PMR medium and recording a codeword in which the generated CRC parity bits are added to the source information sequence; and reading the recorded codeword and an error event in the read codeword. It is possible to detect error events when a codeword recorded by PMR is read, using a small number of bits.
