摘要： A method for seeking the center of a data track recorded on a magnetic tape using a read head, having an accuracy which is not limited by the stepper mechanism which positions the read head relative to the tape, makes use of the discovery that the fundamental component of tape wander is independent of the tape cartridge vendor and the tape length, and therefore the tape wander can be averaged over an integral number of tape wander periods. In the method, the average output from a read head over an integral number of tape wander periods is found at the lower and upper edges of a data track. The read head output from the center of the track is then measured, and is used to calculate an output change versus head position when the read head is partially in the track. The output change versus head position is then used to scale the lower or upper edge position to a position which would result in an output equal to the output found for the opposite edge, and then the center of the track can be found by dividing the sum of one edge position plus the corrected position for the opposite edge by two.

摘要： In a data recording system utilizing multiple channels and data blocks wherein the data blocks are read subsequent to being written so as to check for errors, the data blocks are rewritten according to a method to provide for rewriting only the defective data blocks. The blocks may be rewritten on other than their original channels. Channels for rewriting are determined by selecting a channel with a highest current block number so that data is rewritten in a channel which has been able to write and verify the most of its original blocks. Error checking is continued in a channel even after finding of an error in that channel. Data blocks of the frames may be skewed between the channels at a beginning of the frame. A ring counter output is applied to break a deadlock where a block is continously rewritten on a failing channel.
摘要翻译：在利用多个通道和数据块的数据记录系统中，其中在被写入之后读取数据块以便检查错误，根据提供仅重写缺陷数据块的方法重写数据块。块可以被重新写入其他原始通道以外。通过选择具有最高当前块号的信道来确定用于重写的信道，使得数据被重写在能够写入并验证其大多数原始块的信道中。即使在该通道中发现错误之后，也会在通道中继续进行错误检查。帧的数据块可以在帧的开头处的信道之间倾斜。应用环形计数器输出以打破在故障通道上连续重写块的死锁。
