The invention increases the reliability of a data storage device. The data storage devices contain a memory element disk, containing data, the memory element disk being rotatably mounted about an axis, a transducer head, an actuator for moving the transducer head relative to the disk, and a counter for counting the number of seek operations performed by the transducer head. The invention may include setting a threshold seek value Tseek and comparing this value to the actual seek performed by the head, Vseek, to determine the need for a stop/start operation. Alternatively, the invention includes defining threshold seek operation count Tseek, counting the number of seek operations to determine Mseek since the last stop/start operation, recalling the total number of seek operations completed by the data storage device to define Nseek, defining Dseek by determining the difference between Nseek and Mseek, and determining whether Dseek is equal to or greater than Tseek. When Dseek is equal to or greater than Tseek, the transducer head undergoes a stop/start operation. Mseek may then be reset to equal Nseek before the stop/start operation is undertaken. When Dseek is less than Tseek the count is commenced. The invention may also be used with devices that additionally have auxiliary memory and with arrays of data storage devices. <IMAGE> |
