MAGNETIC DISK DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18537486 titled 'MAGNETIC DISK DEVICE
The abstract describes a patent application for a system where a Host Data Controller (HDC) receives data segments from a host, adds a code to each segment, calculates exclusive OR with respect to the codes, and outputs information. A Read-Write Controller (RWC) performs data conversion and exclusive OR calculations on the data segments, outputs the converted data segments and track parity, acquires codes, calculates exclusive OR with respect to the acquired codes, and compares information.
- HDC receives data segments from a host and adds a code to each segment.
- HDC calculates exclusive OR with respect to the codes and outputs information.
- RWC performs data conversion and exclusive OR calculations on the data segments.
- RWC outputs the converted data segments, track parity, and acquires codes.
- RWC calculates exclusive OR with respect to the acquired codes and compares information.

Original Abstract Submitted
According to the embodiment, an HDC receives a plurality of data segments from a host, and executes generation and addition of a first code and output of a data segment to which the first code is added to each data segment. An HDC calculates exclusive OR with respect to the first codes, and outputs obtained first information. The RWC performs data conversion and calculation of exclusive OR on the plurality of data segments to which the first code is added, and outputs the plurality of data segments after the data conversion and a track parity obtained by the calculation of the exclusive OR. The RWC acquires the first code from the plurality of data segments. The RWC calculates exclusive OR with respect to a group of the second codes which are the acquired first codes to acquire second information. The RWC compares the first information with the second information.
