IPC: G11B7/09
Filed: 1986-08-15
Abstract: PURPOSE:To perform high-density recording by detecting currents which flows to reference patterns made of conductors on a storage medium by the irradiation of an electron beam and detecting the tracking error signal of the beam. CONSTITUTION:The reference patterns PL and PR for tracking which are made of two (x)-directional parallel conductors are provided on the storage medium MM and the currents flows to those patterns PL and PR by the irradiation of the electron beam TEB from an electron beam generation source TEBD for tracking. Lead lines LLL and LLR for leading the currents out are connected to the reference patterns PL and PR and those output currents are converted into voltages, which are applied to a differential amplifier DA through amplifiers AL and AR respectively. Its output is used to compare the quantities of the currents flowing through the patterns PL and PR. The output of the differential amplifier DA is connected to a driver TCD through a phase compensating circuit PRC. The driver TCD applies a voltage which makes a deflection electrode TCR positive and TCL negative when the current flowing through the reference pattern PL is larger than the current of the reference pattern PR.
