Abstract
A high-speed disk drive system that features significant performance improvements over previously available systems. By immediately fetching the data as soon as heads reach the destination cylinder, internally stripping the data across the surfaces and plurality of read/write heads on every surface the data transfer speeds many times depending on other characteristics of the system. By implementing plurality of read/write heads and internal parity surfaces or distributed parity blocks/zones the system achieves higher reliability (fault resistance) with head and surface fail-over fail-safing.
Claims19
An improved operation of disk drive read-ahead (pre-buffering) logic implementing the immediate fetching of data after completing any seek operation, without waiting or skipping sectors coming before the sector addressed by the operation requiring a seek, if any.
An improved operation of disk drive reading and writing technology implementing simultaneous reads and writes on plurality of data surfaces, whatever the data surfaces are for the cylinder where the used heads are, whatever data organization is used and whatever above-mentioned way of achieving precise positioning of all heads at the same time is used.
An improved disk drive system comprising of more than one read/write head or head pair for every surface, being or not being independent of each other, limited or not limited to being on the same cylinder at the same time and being or not being on the same head arm or actuator, limited or not limited to being on the same zone at the same time, whether the heads have fixed positions or not, whatever the total number of heads or heads per arm is used, whatever the implementation, technology, materials or manufacturing process is used for any single component of the said system and whether all or only some heads are capable of either reading or writing data.
A way of achieving the fine-positioning of hard disk drive heads by means of additional piezo-electric effect driven mechanism mounted on main (base) actuator arms for the purpose of achieving either faster head positioning time or local head movemenet independece or both.
