Write data write-pre-compensation system in a floppy disk drive unit and apparatus therefor |
摘要 |
A write data compensation system compensates original write data which is recorded on recording disc mediums, the original write data to eventually be reproduced using a disc drive apparatus capable of reproducing data from recording media having differing recording densities. In the event that the write data is to be recorded on a low density recording media, the original write data is corrected by displacing each bit for which a bit shift is estimated to occur during reproduction in a direction coincident with a direction of the estimated bit shift. In the event that the write data is to be recorded on a higher density recording media, the original write data is corrected by displacing each bit for which a bit shift is estimated to occur in a direction opposing the direction of the estimated bit shift.
