What Is Density Logging?
Recording density usually refers to the amount of binary information stored within a unit length. Disk storage is represented by track density and bit density; tape storage is represented by bit density. The number of tracks per unit length of the magnetic disk in the radial direction is the track density, and the unit is expressed in bpmm (bit / mm) or bpi (bit / inch).

- Recording density usually refers to the amount of binary information stored within a unit length. Disk storage is represented by track density and bit density; tape storage is represented by bit density. The number of tracks per unit length of the magnetic disk in the radial direction is the track density, and the unit is expressed in bpmm (bit / mm) or bpi (bit / inch).
- The volume of binary information that can be recorded per unit area of a recording medium is called "area density" and is expressed in bitslmm2 (bits / mm2) or bltS / in2 (bits / inch2). The above-mentioned method is called data recording density. One representation method refers to the number of magnetic flux reversals that can be recorded per track length. It is called the physical recording density, and the unit is ftp ~ or ftlmm magnetic flux reversal / mm. The corresponding data recording density is 32bpmm, 646pmm, 246bpmtn or 8U (lbpin, 1fi006pin, 6250bpin. The quantitative relationship between the physical recording density and the data recording density varies depending on the encoding method. [1]
