Magnetic recording/reproducing apparatus

一种磁记录再生装置，通过附加满足目标的错误率的所需最小限度的冗余字节，从而减少不必要的被附加的冗余字节，并减小冗余字节所引起的驱动器的重写。并根据进行写入的介质(11)的缺陷状况和电路特性、及写入该数据的写磁头、以及对已写入的数据进行再生的MR磁头的电路特性等，在格式化块(6)中改变附加的冗余字节的大小。 In a magnetic recording playback device, since minimum redundant bytes required for satisfying a target error rate are added, the addition of more...

Summary:一种磁记录再生装置，通过附加满足目标的错误率的所需最小限度的冗余字节，从而减少不必要的被附加的冗余字节，并减小冗余字节所引起的驱动器的重写。并根据进行写入的介质(11)的缺陷状况和电路特性、及写入该数据的写磁头、以及对已写入的数据进行再生的MR磁头的电路特性等，在格式化块(6)中改变附加的冗余字节的大小。 In a magnetic recording playback device, since minimum redundant bytes required for satisfying a target error rate are added, the addition of more redundant bytes than are necessary is reduced, whereby overwrite of the drive due to the redundant bytes is reduced. The size of redundant bytes to be added in a formatter block is varied according to the defect condition or electric characteristic of a medium on which data are to be written, or the electric characteristics of a write head for writing the data and an MR head for reproducing the written data.
