The basic wave and the higher harmonic are converged on the optical recording medium 25 by an objective lens 24 through a half prism 23. Thus, the basic wave and the second higher harmonic are used. Thus, information can be recorded at high density by a spot smaller than the size of the spot of the second higher harmonic at a recording mode by using the semiconductor laser of low output as the semiconductor laser 21. Then, a noise component becomes smaller compared to a case when information is read from the reflected light of the basic wave whose size of the spot is large and accordingly information can accurately be read.

Title: Input/output control method
Inventor: MINAMIURA KIYOTO
IPC: G06F13/14
Filed: 1990-07-02
Abstract: PURPOSE:To avoid a dead lock resulted from the difference of a host efficiency by counting busy information at the side of a device, holding the command of the inputting/outputting process at the side of the device when the count is continuous and the number is beyond a constant value, and processing the command preferentially when the device is opened. CONSTITUTION:When a busy state is informed, according to the issue of the inputting/outputting process from one of the hosts, for example, a host #1, to a drive(device) #0, the busy information is counted at the side of the device #0. Then, when the count is continuous and the number is beyond the constant value, the command of the inputting/outputting process from the host #1 is held at the side of the device #0. When the drive(device) #0 is opened, the held command is taken out and processed preferentially. Therefore, the input/output request at a low speed for the drive #0 is processed in the same way as the input/output request is issued at a high speed. Thus, the dead lock state can be avoided even when plural hosts #1, #2, which have the difference of the efficiency share the drive #0 with each other.
