Abstract
A hard disk drive comprises an actuator with independently movable arms and a printed circuit board with custom core electronic architecture. The drive also comprises one or more platters aggregating two or more platter surfaces whereupon data may be read from or written to by corresponding read/write heads. The independent-arm actuator and custom printed circuit board enable alternate or interleaving bits or blocks of data to be read or written simultaneously across a plurality of platter surfaces within the same physical drive.
Claims77
An information storage and retrieval apparatus, said apparatus comprising:
- at least one circular substrate, said substrate or substrates aggregating at least two carrier surfaces capable of storing data whereupon data may be read from or written to by corresponding read/write members;
- and means for simultaneously and independently reading or writing alternate or interleaving bits or blocks of data across each of said plurality of carrier surfaces within said information storage and retrieval apparatus.
An information storage and retrieval apparatus, said apparatus comprising:
- at least one circular substrate, said substrate or substrates aggregating at least two carrier surfaces capable of storing data whereupon data may be read from or written to by corresponding read/write members;
- an actuator mechanism with at least two arms, each of said arms assigned to different carrier surfaces;
- means for moving said arms simultaneously and independently across corresponding carrier surfaces with a component of movement in a radial direction with respect to the circular substrate or substrates defining the carrier surfaces;
- and a logic holder, said holder comprising electronic architecture for electronically controlling said information storage and retrieval apparatus, wherein in its operative mode, said information storage and retrieval apparatus executes means for permitting alternate or interleaving bits or blocks of data to be read or written simultaneously and independently across a plurality of carrier surfaces.
An actuator mechanism, said mechanism comprising at least two arms, said arms assigned to different circular carrier surfaces within an information storage and retrieval apparatus;
- and means for moving said arms simultaneously and independently across corresponding carrier surfaces with a component of movement in a radial direction with respect to said carrier surfaces.
A logic holder, said holder comprising:
- electronic architecture, said architecture implementing means for electronically controlling an information storage and retrieval apparatus, wherein said information storage and retrieval apparatus comprises at least one circular substrate, said substrate or substrates aggregating a plurality of carrier surfaces whereupon data may be read from or written to by corresponding read/write members simultaneously and independently;
- said information storage and retrieval apparatus further comprising an actuator mechanism with a plurality of arms and means for moving said arms simultaneously and independently across corresponding carrier surfaces with a component of movement in a radial direction with respect to the circular substrate or substrates defining the carrier surfaces.
