Title:
MAGNETIC DISK CONTROL PART
Document Type and Number:
Japanese Patent JPH0528667
Kind Code:
A
Abstract:
PURPOSE:To prevent the waiting rotation of a magnetic disk device from entering by a correction processing when a correction possible ECC error exists in read data from the magnetic disk device. CONSTITUTION:An inner part memory 40 storing data belonging to an ECC part for the portion of required one transfer sector number is provided and read data belonging to the ECC part read from the magnetic disk device 200 is written in the inner part memory. A system is provided with a function where a data part except the ECC part is simultaneously transferred to a main storing device 500 so that data stored in the inner part memory 40 is corrected and transferred to the main storing device 500 after the termination of reading from the magnetic disk device 200. Thus, waiting rotation due to the correction processing is not generated so that there is an effect that a read operation is shortened even if lots of ECC read errors occur.
