Title:
【発明の名称】ディスクドライブにおける過渡的な書き込みエラーを検出し、過渡的な書き込みエラーと永久的なメディアの破損とを区別するための方法
Document Type and Number:
Japanese Patent JP2003511813
Kind Code:
A
Abstract:
Methods are provided for detecting transient write errors based on difficulty in reading pre-recorded information on a disk such as servo marks, ID marks, etc. In the event of such a difficulty, the disk drive will automatically read the data it just wrote. If errors were encountered during this write process, the disk drive will either rewrite the data or report errors to the host system which will in most cases issue a rewrite operation. The methods also distinguish between transient errors and permanent media damage and reallocate permanent disk damages to prevent further loss.
