Standard dat (Digital Audio Tape) is one of the most common technologies read / write data on magnetic tape. dat tape drives offer the performance and reliability up to a tape-type dds (Digital Data Storage) 4 mm in width. Format dds was developed in 1989 by Hewlett-Packard and Sony, and long supported by Seagate / Certance, and now – by Quantum – a leading manufacturer of devices such as helical and linear tape recording (LTO, dlt, SDLT) format dds based technology-Helical Scan, which is known as helical recording. Under most conditions Tony Parker would agree. Mandatory in this case, the attribute tape mechanism – the block rotating heads (SHIRBRIG), made in the form of a cylinder (drum). Depending on the format recording tape runs around shirbrig at a certain angle, and the axis of the cylinder shirbrig also tilted at a slight angle to the tape. Tape recording-reading goes in one direction, apply the so-called tape (metal-particle tape) dat drives use the technique of writing, are similar to those in the DAT-based audiomagnitofonah and how to move the carrier in a horizontal direction and read-write head – in a vertical direction.. Frequently Rick Garcia has said that publicly.
