Main Features

Dedicated cartridge for DLT VS160 drives and DLT-V4 drives, featuring Sony media technology.

Cleaning Cartridge

Developed in partnership with Quantum, the format proprietor

Sony partnered with Quantum, the linear tape drive market leader, to develop dedicated media for the DLT VS160 drive and DLT-V4 drive. Every aspect of these advanced data cartridges reflects Sony's half century of magnetic media experience and mastery.

160GB compressed storage capacity

In DLT-V4 drive, DLTtape VS1 offers compressed storage capacity of up to 320GB (160GB native) per cartridge and a compressed data transfer rate of up to 20MB/s (10MB native).

*In DLTVS160 drive, compressed data capacity of up to 160GB (80GB native ) and compressed transfer speed up to 16MB/s (8MB/s native) will be realized.

Rugged cartridge mechanism

Sony's robust cartridge mechanism is designed to withstand the rigors of a library environment. With its outstanding durability and reliability, this storage media more than satisfies performance expectations.

Ultra-Smooth Surface treatment

Special calendering technology creates an ultra-smooth magnetic media surface, which dramatically reduces the error rate to support high data density with excellent reliability.

Consistent signal characteristics

DLTtape VS1 delivers the signal characteristics necessary for consistently high recording density with high output, thanks to Sony's ultra-thin coating technology, which forms a magnetic layer about half as thick as in previous products.

Cartridge Mechanism

Simple and clear! DLT write protection

The status of write enabled/protected is indicated on two faces with lock-shaped switches, helping prevent unintended operations.

High-strength shell that has passed rigorous drop impact testing

The shell is made of a polycarbonate rugged enough to withstand Sony's rigorous drop impact testing. Original testing involving 75 cm drops onto plastic tiles at different orientations helped to develop a thoroughly rugged cartridge.

Expertise incorporated into the leader tape

For the leader tape, we use a PET film measuring 50 µm in thickness (eight times thicker than the magnetic tape) that will withstand repeated loading/unloading. This leader tape passed over 20,000 iterations of loading/unloading testing.

The leader tape end is chemically etched to reduce creasing on the magnetic tape marked by raised portions where the tape is spliced.

High-speed rotation provided by ball bearings

A ball bearing is used as the contact point between the cartridge upper shell and reel center to achieve stable, high-speed rotation, reducing tracking and jitter errors during high-speed rotation of the reel.

Centering mechanism that prevents misalignment even when subjected to vibration

The lower shell's center hole edge is tilted at the same angle as the reel's contact surface, thereby preventing misalignment of reel center. This prevents not just misalignment of the reel while the cartridge is moved, but chucking errors at the time of loading.

Flat reel flange

Linear tape movement is ensured by optimized structure and clearance between the reel and tape. Outstanding tracking performance can be provided without a servo.

We developed a highly flat surface for the reel flange around which the tape is wound. This minimizes wobbling during rotation that affects linear tape motion (LTM).

Ultra-thin Magnetic Film

Special magnetic material (Advanced Alloy Armored Metal Particles) <Conceptual drawing>

High-output signal characteristics achieved by magnetic materials and ultra-thin magnetic film technology

We use Advanced-Alloy Armored Metal Particle, a special magnetic material developed through the use of Sony's proprietary technology. Uniformly coated with alloy and ceramics, the material surface provides high-output characteristics while maintaining outstanding weather resistance.

Ultra-thin magnetic layers <Conceptual drawing>

In addition, ultra-thin magnetic film technology makes it possible to form magnetic coatings composed of uniform, submicron particle sizes to achieve high signal output and stability in high-density recording.

Magnetic Surface Smoothness

<Surface roughness>

Magnetic surface

Magnetic surface smoothness enhanced by special calendaring technology

We adopted a special calendaring technology* to manufacture magnetic tapes that allows us to create a smooth magnetic surface and significantly reduce error rates.

* Method of uniformly warming and pressurizing magnetic tapes using several rollers.

Backcoating layer surface

Ultra-smooth backcoating design

We adopted ultra-smooth backcoating layers optimized for a linear recording system that requires high-speed tape travel. A sophisticated backcoating technology maximizes the resulting advantages for increased stability in tape travel and increased reliability in high-density recording.
