HIGH RELIABILITY STORAGE DRIVE AND DATA WRITE METHOD

摘要

A MAGNETIC DISK DRIVE CAPABLE OF SHORTENING A FLYING TIME OF A MAGNETIC HEAD (2) FLYING OVER A MAGNETIC DISK (1) AND REDUCING THE NUMBER OF LOAD/UNLOAD OPERATIONS.THE DISK DRIVE INCLUDES A NON-VOLATILE MEMORY (5) FOR TEMPORARILY STORING DATA CORRESPONDING TO A WRITE COMMAD (251, 261, 271)SUPPLIED FROM A HOST(11).DATA CORRESPONDING TO A PLURALITY OF WRITE COMMANDS ARE STORED IN THE NON-VOLATILE MEMORY.THE HEAD LOADING IS SUSPENDED UNTIL A PREDETERMINED CONDITION IS SATISFIED.WHWN THE PREDETERMINED CONDITION IS SATISFIED, ALL THE DATA STORED IN THE NON-VOLATILE MEMORY ARE WRITTEN IN THE MAGNETIC DISK SEQUENTIALLY AT A TIME.THEREBY IT IS POSSIBLE TO SHORTEN THE FLYING TIME OF THE MAGNETIC HEAD FLYING OVER THE MAGNETIC DISK AND REDUCE THE NUMBER OF LOAD/UNLOAD OPERATIONS.FIG. 1
