Finally, the drive electronics synchronize the scanners and intensity modulator with the incoming video signal in such a manner that a stable image is formed.
Due to the second fact, an unmodified 4FDC can not be used with 8-inch drives that don't have single-density data separators on the drive electronics.
More costly - Inductive charging also requires drive electronics and coils in both device and charger, increasing the complexity and cost of manufacturing.
Newer approaches reduce transfer losses through the use of ultra thin coils, higher frequencies, and optimized drive electronics.
In effect, Iomega has split apart a standard external hard drive, separating the expensive drive electronics from the spinning platters that actually store the data.
But in this way, only half (plus one) the number of hammers, magnets, and the associated channels of drive electronics were required.
Feedback of the drive electronics is accomplished by means of special segments of the disk dedicated to servo feedback.
The tape recorder's drive electronics use signals from the tachometer to ensure that the tape is played at the proper speed.
Remove the four screws and sled from the HDD, taking care to avoid touching the integrated drive electronics.
The advantage of half stepping is that the drive electronics need not change to support it.
