102 Disc Storage DriveAdvantages
Sealed EnvironmentA carefully designed sealed environmentprotects the head, media, actuator, andspindle from contamination and utilizesan absolute filtration system inside theenclosure.
Disc Coating CharacteristicsOxide particles in the coating arecircumferentially aligned to provide highsignal output and high resolution.Memorex 1OOX coating surface shieldextends the useful disc life over 100times the life of discs not coated.
Easy ServiceabilityBy integrating the drive motor with thehub, we have eliminated belts andlowered parts count which increasesreliability and saves valuable space. Theelectronics package mounts to the bottomof the head/disc assembly (HDA) foreasy field service access even while thedrive is running.
Data SeparatorThe 102 disc drive receives write data inNRZ code and also transmits read datain NRZ code. NRZ data is MFM encodedand decoded to and from the media bya phase locked data separator in thedrive.
Low Power ConsumptionMinimal power is required to operate theMemorex 102 which lowers system costs.What's more, only DC power is necessaryallowing for international versatility.
