Preface

Data loss

For MAS series, Reed Solomon codes are applied for their ECC. The sector-data is divided into 4 interleaving sectors, and ECC is performed in each sector where the maximum number of errors (up to 5 byte) can be corrected. [Total maximum byte: 5 byte × 4 ( interleave) = 20 byte]

If the error of read sector keeps allowable error byte number, correction is performed. However, if error byte exceeds its allowable number, correction may not be performed properly.

The main alert messages in the text are also listed in the “Important Alert Items.”
