ABSTRACT:
A data write control method of a hard disk di ive which can prevent the loss of data by sensing an abnormal flying height of a transducer head luring a data write operation. In the method, servo information is read from a write medium to compare an amplitude level of the servo information with a prescribed setting value. If the amplitude level of the servo information is less than the setting value, a flying height of a transducer head from the write medium is determined not suitable for the data write operation. A write disable flag is set to change the disk drive to a write non-ready state until the flying height of the transducer head is suitable for the data write operation.
