ABSTRACT:
Disclosed is a dynamic range control circuit for determining when to allow an error correction circuit to correct data read from a sector of a disk data storage device. The circuit has two sets of registers used to count bytes of information within a sector. A first set of registers counts bytes as the sector is being read from the disk, and accumulates a count of a pre-data field and a count of a data field. These counts are then loaded into a second set of registers, along with a count indicating the length of the redundancy field within the sector. As correction is being performed, the second set of registers is decremented and the values in the registers used to set an in-range signal which allows a correction to the data field and prevents correction to the pre-data or redundancy fields.
