Scalable Linear Recording (SLR) is a tape storage technology that uses the longitudinal track method in recording and uses cartridges with 8 mm magnetic tapes. SLR series tape drives are suitable for entry- level, mid-range and high-end server use.
The storage capacity of SLR cartridges ranges from 4 gigabytes( GB) to 140 GB, the data transfer rate is 600 MB/min and the average access time( AAT) is between 45 s and 65 s, depending on the drive type. To increase storage capacity and data throughput and reduce access times, SLR drives feature multi- channel linear recording systems, Multichannel Linear Recording( MLR).
SLR technology was developed as early as 1970 and was significantly influenced by Tandberg Data.
Magazine boxes for eight SLR cartridges are available as autoloaders, giving the SLR140 autoloader a storage capacity of 1.120 terabytes( TB) for compressed data. In addition to its 140 GB storage capacity, the SLR140 features a data transfer rate of 12 MB/s for compressed data. The connection to the server is made via Ultra- SCSI, and an 8 megabyte (MB) buffer memory acts as a buffer, ensuring continuous data transfer. The cartridges are managed using barcodes and barcode readers.
