Auto Head Parking

Fall to the surface with a characteristic “crackle”. At the same time, they tear off microscopic particles from the surface, consisting of particles of the working layer of the carrier.

It is believed that drives can withstand thousands of “takeoffs” and “landings” of heads. Therefore, the rule – do not turn off the computer during the working day – is relevant. The fewer on-offs, the more likely the computer will not fail, the higher.

It was experimentally verified that even minor mechanical impacts on the drive during takeoffs and landings significantly increase the likelihood of damage to heads and disks.

Zip Iomega: differences
When the supply voltage is applied, the spindle motor spins the disc to 2941 rpm.

The head block design in the Zip Iomega is quite simple. Each head is mounted on the end of the lever on the spring, slightly pressing it to the disk. Few people realize that without movement, the disk is as if clamped between a pair of heads (bottom and top).

Unlike HDDs, Zip heads are not located in the working chamber all the time; they are inserted into the cartridge during operation and displayed after the end of work with Zip Iomega. In our opinion, this is a very significant difference, compared to the HDD, which is a factor in reducing the reliability of the device. The HDD heads are in constant airflow, and the Zip heads have to enter the turbulent zone abruptly, and they enter the working area with a ski jump.
The “springboard” is needed in order to unclench the heads at the beginning of their launch with the creation of a gap between the heads more than the thickness of the disk. The “springboard” is created by a special device mounted on the carriage of magnetic heads, and consists of a pair of gable plastic ramps and metal extractors mounted on each of the heads (see Fig. 2). At the start of the heads from the place of their parking, the extractors bump onto inclined surfaces (“springboards”), unclench and, “smoothly” moving out (according to the designers’ ideas) along the slope behind the “springboard”, together with the heads lower to the disk, where they are picked up and held by some distance from the surface of the disk air flow. It is not surprising that in such a mechanism such a malfunction as a cliff of extractors is quite common.

Excellent coprocessor (FPU)
