IPC: H01S3/08
Filed: 1989-11-20
Abstract: PURPOSE:To more stably control the oscillation wavelength of a semiconductor laser by providing a Fabry-Perot resonator formed of two types of optical materials having different signs of temperature coefficients between a semiconductor laser and a photodetector. CONSTITUTION:A Fabry-Perot resonator 20 formed of two types of optical materials 21, 22 having different symbols of temperature coefficients gamma (gamma=alpha+(1/ n).(dn/dt), where alpha is a linear expansion coefficient, n is refractive index, dn/dt is change amount of refractive index to a temperature) is provided. Accordingly, the physical lengths of the materials 21, 22 are regulated to set the temperature coefficient of the entire resonator to zero, thereby setting the resonator length of the resonator 20 to temperature change constant. Thus, the length of the resonator 20 is not varied with respect to the temperature change, and the oscillation length of a semiconductor laser 1 can be remarkably stably controlled.

Title: Erasing device
Inventor: YAMAGATA SHIGEO
IPC: G11B5/024
Filed: 1986-12-16
Abstract: PURPOSE:To freely select a range in setting an erasing range by respectively specifying a block where erasure should be started and a block where deletion should be completed and automatically erasing the range. CONSTITUTION:An erasure means is provided, which erases in the specified range of the block where the erasure should be started and the block where the erasure should be completed. In a field erasure, for example in the case of erasing only a track reproduced by a magnetic head 3-1, a control signal is transmitted from a CPU 40 in order that a SW 2 is switched to a recording amplifier side and a SW 3 is switched to be in a middle state on starting the erasure. Moreover an erasure signal trigger pulse is transmitted from the CPU 40 to an erasure signal generator 85 in order to send the erasure signal only to the head 3-1. Since the erasure signals are simultaneously sent to the heads 3-1 and 3-2 at the time of erasing a frame, the control signal is transmitted from the CPU 40 in order that the SW 2 and SW 3 are simultaneously switched to the recording amplifier side. And the erasure signal is generated with the trigger pulse and sent to both heads through the recording amplifier. Thus an erasing device, which is easy to be used, can be obtained.
