SDLT
Super DLT Platform lineup with new technical features 160GB (Native), 320GB (Compressed)
Ultra-smooth tape surface and thin magnetic-layer tape technology
The SDLT platform achieves tremendous storage capacity by using MRC Magneto Resistive Cluster heads for high data density recording. However, this new head technology is so sensitive that it increases noise from the media along with output. To solve this problem, Sony has greatly reduced the spikes on the tape surface so the tape can run without generating surface noise.
POS: Pivoting Optical Servo for higher track density
To assure accurate tracking of its increased data tracks, the SDLT format uses a tracking servo, unlike the lower-density DLT. This innovative POS (Pivoting Optical Servo) tracking system precisely handles the high track density of SDLT by reading permanent optical guidance tracks etched on the back of the tape. Based on the positioning data read from these tracks, the servo adjusts the MRC head position for correct alignment with the target data tracks on the magnetic side of the media. Of course, the non-contact laser optics do not damage the tape.

PRML: Partial Response Maximum Likelihood
In addition to the recording technology of the DLT4 format, SDLT adopts a more sophisticated data channel, PRML. PRML enhances reliability of data read from the tape and also helps achieve high-density recording.
Positive Engagement Tape Leader Buckling Mechanism
The Super DLTtapeTM cartridge adopts a new buckling system design at the end of tape, which enhances reliability under heavy usage cycles, such as with automated equipment. Plastic materials used in this mechanism are highly robust to resist wear despite repeated loading and unloading.
