Design principles

Storage device, idealHigh capacity

Access speed

Low/no; power/energy

Storage device, hybridPhysical/electronic

Page or packet vs. bit

Low/no(stored); power/energy


Dataslide, why?

Background, professional problemEx-sys prog.

Materials, mature technologiesMaterial specifications far exceed the immediate requirements

SkillsMan centuries

CommercialCorporate support, not corporate control


Dataslide: The Concept

A hard disc(HDD) is:- A dataslide(HRD) is:-

Round and spins Rectangular and oscillates

Requires registration, No registration

Zero dimensions, Two dimensions

Both have:-

Permanent magnetic media

Industry standard interfaces

Common enclosures / form factors


Sectors and data organisation

Dataslide comprises linear arrangement of sectors:

Hard disk driveOne head for all sectors

Central and corner areas unused

dataslideOne head per sector

Maximum use of media area

±80μ @ 800Hz 96,000rpm equiv. 10,000rpm


dataslide: the concept

Media plate

Read:Write head matrix

Actuator


Dataslide: The Advantages

Access speed (no seek, very low latency)

Low lifetime power requirement

Silent, with acoustic coupling

‘Page’/RAM mapping.

De-fragmentation not required for performance

Mature materials, ideas and technologies

Elegance, not ‘brute force’


Dataslide: The Technology

Corning ULE™ glass substrate

Piezo-electric actuator

taC solid lubricant

Lithography read:write heads

Media Industry standard

Available electronic IP ASIC


Dataslide: cultural emphasis

‘Genealogy’ of dataslide systems.

Generation 1

Hard drive; HRD

Generation 2

RAM, cache

Generation 3

State safe machine with processors

Generation 4

Cognitive, state safe, “n” dimensional, physically connectionless

Generation 5

Cognitive, learning, deductive, physically connectionless, active coalescence

Refined contents addressable storage

Very low latency, high bandwidth

Low latency mass storage

Massively parallel computer, AI

Perceptron neural net, RI
