The EXB-8500 and EXB-8500c 8mm tape drives use helical-scan recording technology and read-and-write head pairs to achieve an uncompressed data transfer rate of 500 KB/sec. The EXB-8500c extends the performance of the EXB-8500 to a 10 GB capacity at a 1 MB/sec transfer rate (compressed). The EXB-8500 reads and writes 8200 and 8500 formats; the EXB-8500c writes 8200, 8200c, 8500, and 8500c data formats. The tape drives are designed to perform onboard error correction and error recovery, along with full read-after-write verification to ensure data integrity. The tape drives are available in two configurations: as internal tape drives and as external drives that provide the convenience of a standalone peripheral.
