Systems and methods are disclosed for write fault modulation. In an embodiment, an apparatus may comprise a circuit configured to adjust a write fault value for a data storing system based on a circumferential point of a target data storage location, and write data based on the write fault value. The write fault value may represent an amount of off-track deviation of a data writing system within which data writing operations may be performed. In another embodiment, a memory device may store instructions that cause a processor to perform a method including receiving a write command including write data, determining a write fault threshold for a circumferential point of a target location of the write data, performing, using a transducer, a write operation at the circumferential point based on the write fault threshold, and suspending the write operation when a positional deviation of the transducer exceeds the write fault threshold.
