| | Double density - Wikipedia, the free encyclopedia |
 | | In 3½ inch floppy disks using IBM PC compatible MFM format, double density marks a disk format that uses 9 sectors of 512 bytes per track, for a total capacity of 720kB in a two-sided 80 track floppy disk. | | | 3½ inch floppy disks most commonly used in the latter 1990s and the 2000s were high density, which increased the capacity to approximately 1440kB. | | | The term double density can also be applied to magnetic tapes. |

| | Patent 4462088: Array design using a four state cell for double density |
| | Another object is to achieve almost a one hundred percent increase in storage capacity with the same number of single device cells as are conventionally formed in storage arrays; in other words, to virtually double the storage available in a given array size. | | | This effectively doubles the information content for an array with litle increase in the array size. | | | Accordingly, it is a primary object of the present invention to realize a simple and efficient ROM or ROS system having two-terminal storage cells which can store four levels or states. |

| | Sony is reportedly developing a 3GB rewritable DVD, but also has a huge interest in supporting the CD format, which originated in the laboratories of the company's longtime partner, Philips Electronics. | | | Manufacturers will be able to upgrade their CD drives by changing laser assemblies, according to Yoshiko Hara of Electronic Engineering Times. | | | Intended for the computer market, Sony's new system employs a shorter track pitch and a minimal pit length to increase the capacity of the discs from 650MB (MegaBytes) to 1.3GB (GigaBytes). |
