Title: Rotating speed control method
Inventor: TSUJI KENTARO
IPC: G11B19/28
Filed: 1986-11-27
Abstract: PURPOSE:To drastically increase a recording capacity of a disk by counting a length between mark bit pattern edges, detecting its bit pattern of mark and controlling the rotation of a discoid recording medium to be a constant linear speed based on the detected count value. CONSTITUTION:A length between mark pattern bit edges is counted by using a clock which has a frequency as 64 times as many as the mark pattern bit rate at the time of the mark detection. Therefore, when the disk is normally rotated, the length between edges of 1T is counted as 64 clocks and that of 4T as 256 clocks. When a ratio of 1T to 4T is calculated resulting in four whatever the rotating speed of the disk may be, and the same result is continuously obtained twice, the mark can then be decided. Consequently, a ratio of a count number of 4T to a normal count number of 4T under normal condition is calculated and then multiplied by an essential disk linear speed to be the existing disk linear speed, and then the rotation of the disk is controlled to be at a constant linear speed. Thus, the recording capacity can eventually be increased.

The relaxation time of free carriers is determined by a tunnel time constant, but the value is faster than the recombination time of free carriers, thus largely increasing the working speed of an element.
