Filed: 1987-02-04
Abstract: PURPOSE:To speed up the effective transfer rate of data by segmenting and transmitting plural continuous data stored in a block buffer register in response to a request unit. CONSTITUTION:Plural continuous data received from an input/output processor 1 and stored in a buffer memory 32 are transferred all at once to a buffer register 31 via parallel processing and held there.

Title: Magnetic erasing system
Inventor: SAKAI KUNIHIDE
IPC: G11B5/024
Filed: 1983-02-18
Abstract: PURPOSE:To attain an easy and complete magnetic erasing system by using an erasion head under a heating state of a magnetic recording medium. CONSTITUTION:A magnetic recording medium 1 traveling in the direction of an arrow mark is heated up to about 100 deg.C, for example, by means of a high frequency heating means. Thus the medium 1 is locally heated, and at the same time an erasing magnetic field is impressed to the medium 1 by an erasion head 2. Then the magnetization M of the locally heated area of the medium 1 can be turned easily toward the direction of an external magnetic field. In other words, the magnetic field needed to give orientation to the magnetization M, i.e. a magnetic field Hc needed for magnetization of the medium 1 into a saturated state in order to erase completely the recorded signal is reduced as the temperature rises. Then the recorded signal can be erased with such a weak magnetic field that cannot be erased at a room temperature. Thus the recorded signals are successively erased in response to the traveling of the medium 1. The magnetic erasion is simple and complete since the medium 1 is heated up. As a result, even a magnetic recording medium having especially a high level of reluctance force can be erased with a weak magnetic field.
