ANSI/ISO/IEC 15757:1998 信息技术.8 mm宽盒式磁带的数据交换.螺旋扫描纪录.INCITS采纳的DA-2格式

Specifies the physical and magnetic characteristics of magnetic tape cassettes, using magnetic tape 12, 65 mm wide so as to provide physical interchange of such cassettes between drives. Also specifies the quality of the recorded signals, the recording method and the recorded format, called Digital Tape Format-1 (DTF-1), thereby allowing data interchange between drives by means of such cassettes. The format supports variable length Logical Records, high speed search, and the use of a registered algorithm for data compression. This International Standard specifies two sizes of cassette.

ISO/IEC 15498:1997 信息技术.90mm盒式光盘上的数据交换.HS-1格式.容量:每盒650Mbytes

This International Standard specifies the characteristics of 90 mm Optical Disk Cartridges (ODC) with a capacity of 650 Mbytes per Cartridge. The Standard specifies three related, but different implementations of such cartridges, viz. Type R/W Provides for data to be written and read many times over the recording surface of the disk using the thermo-magnetic and magneto-optical effects. Type P-ROM Provides for a part of the recording surface of the disk to be embossed by stamping or other means. This part of the disk is read without recourse to the magneto-optical effect. The part which is not embossed provides for data to meet the requirements of Type R/W. Type O-ROM Provides for the recording surface of the disk to be embossed and reproduced by stamping or other means. This type of disk is read without recourse to the magneto-optical effect. Type R/W, Type P-ROM and Type 0-ROM are also referred to as "fully rewritable", "partially embossed" and "fully embossed", respectively. This International Standard specifies - the conditions for conformance testing and the Reference Drive; - the environments in which the cartridges are to be operated and stored; - the mechanical and physical characteristics of the cartridge, so as to provide mechanical interchangeability between data processing systems; - the format of the information on the disk, called HS-1 (HS stands for "Hyper-Storage"), including the physical disposition of the tracks and sectors, the error correction codes, and the recording method used; - the characteristics of the embossed information on the disk; - the magneto-optical characteristics of the disk, enabling processing systems to write data onto the disk; - the minimum quality of user-written data on the disk, enabling data processing systems to read data from the disk. This International Standard provides for interchange between optical disk drives. Together with a standard for volume and file structure, it provides for full data interchange between data processing systems.
