Quantum uses the LGMR (Laser Guided Magnetic Recording) process in its reliable and dependable DLT tape format. DLT is an advanced backup storage media platform that supports its multiple versions. Four major innovative technologies are used in the Quantum SDLT (super DLT) backup tape format. These reliable technologies are POS (Pivoting Optical Servo), MRC (Magneto Resistive Cluster) head, PRML channel and AMP (Advanced Metal Powder) media. SDLT tape format is integration of innovative, powerful and reliable technologies that provide low cost and durable backup solutions.
Metal powder mechanism is used in the advanced metal powder media that is useful in very high data recording densities. In AMP media, there are optical-guidance targets that are on the media's backside which are previously unused. AMP tape media also consists of optical-servo tracks. On the upper side of the SDLT tape is the optical guidance tracks while on the lower side of the data tape are the magnetic data tracks. MRC comprises of cost effective, densely packed small cluster of magneto resistive tape heads. Thin film processing mechanism is used in the MRC heads. Multiple heads increase the performance, output and transfer rate of Quantum Super DLT technology. Quantum SDLT tape technology is less susceptible to the environmental factors which as result increases the tape format's track density and the ability to store more data. POS (Pivoting Optical Servo) is invented by Quantum and is utilized in the SDLT technology. POS allows high duty cycles. Data is magnetically recorded and hundred percent of the tape media's front side is utilized.
Quantum SDLT is less sensitive to the outside influences therefore the track count is greater along with supreme performance. Quantum Super DLT uses the efficient PRML channel's new advanced form that offers high efficiency (97 percent) code. Linear density of SDLT is increased by the PRML channel. Superior and exceptional transfer rate & recording capacity of SDLT enables it to manage huge volumes of data generated by the enterprise intelligence systems. The reason to adopt the fast speed SDLT backup storage technology is to match the explosion of information across the business landscape. More storage space and fast backup solution is the major requirement to handle the huge generated data volumes.
More tape area is required to enhance the recording ability and speed to transfer the data. Additional data tracks are needed to boost the recording densities. Per track recording density and more utilization of tape surface for recording of data are very essential. Quantum SDLT has all these latest technologies to provide high output. As described earlier that LGMR is the SDLT tape format's base. This technology is combination of magnetic & optical technologies. The quantity of data tracks tape recording surface in SDLT tape media is increased due to the new technologies of LGMR. Requirement of preformatted data tape is eliminated in Quantum Super DLT because of the Pivoting Optical Servo. PRML channel & MRC (Magneto Resistive Cluster) heads deliver more capacity to save more data and high speed to ensure fast transferring of data. High density in SDLT tape technology is achieved by the advanced metal powder media. Quantum SDLT tape technology has buckling method of tape leader. That is why the duty cycle of Quantum SDLT is high in the automated working environments.
